"Of course it takes three great men to create such a woman."

 

In the now-iconic Mamma Mia! films, soon-to-be-bride Sophie (Amanda Seyfried) invites her three potential fathers (Pierce Brosnan, Colin Firth, and Stellan Skarsgård) to her upcoming wedding, in search of her real dad. This was hidden from her by her mother Donna (Meryl Streep), as she doesn’t know the answer either. 

 

 

 

The question we want to find the answer to is about Sophie’s father. “Doesn’t that go against the message of both films?” you may be asking. Our question isn’t who Sophie’s dad is but who is the best father to Sophie? To get to the bottom of this, we have created a set of criteria to evaluate Sam, Bill, and Harry to figure out who is the best of Sophie’s three dads. We call it the D.A.D.S. system. It stands for “Dynamic” (judging their personality and their relationship with her), “Accessibility” (how much time they spend with her, though it’s hard to judge the real world time they would’ve spent together so we are calculating how much screen time each dad and Sophie share in both movies), “Dependability” (are they there for Sophie when she needs it?), and  “Singing" (not necessary for being a dad, but the Mamma Mia! films are musicala so we are also judging their singing ability). We will be assigning a letter grade to each category and totaling up their D.A.D.S. score to finally determine who is the ultimate dad!
 
DYNAMIC
 
Sam:
Sam is the romantic out of the three dads. He’s the one who broke Donna’s heart, ultimately marrying her when Sophie canceled her wedding. He also is her actual stepfather, as he married Donna and lived on Kalokairi for 5+ years, but, as we’ve mentioned, off-screen development doesn’t count. He has had experience raising children from his last marriage, and though Sophie is a grown woman by the time they meet, it helps him build a good relationship with her. He wants to make up for lost time, not just with Sophie but with Donna too. 
 
SCORE: A for using his past experience to help Sophie in the present.
 
Harry:
Harry is the quirky, anxious, tries-to-be-spontaneous dad. He has a lot of funny moments, being the one to spoil the baby surprise at the end of Mamma Mia! Here We Go Again, and doing the Titanic pose with Harry being Rose. He is also very sweet, singing and playing guitar with Sophie and stating he would “spoil her rotten” if he had a daughter, which he then later finds out he does. All he wants is to be a good father and will do anything to not let Sophie down.
 
SCORE: B+ for his enthusiasm about being a “new” father.
 
Bill:
Bill is the wild, adventurous one of the three, the most famous stud of Europe. He goes on sailing contests, gets into trouble, and lives mostly out of his boat. He just wants to have fun and has lived a life most would be jealous of. Like the others, Bill wants the best for Sophie and tries to be there for her as much as he can. 
 
SCORE: B- for being a fun dad.
 
ACCESSIBILITY
 
Sam:
Sam has a leg up on the other dads in “accessibility” because he has a couple more scenes in Mamma Mia! Here We Go Again. We’ll focus on the sequel, as Sam spends a lot of his time with Sophie, with the other two dads, or with Donna in the first film. Sam's father-daughter time is spent encouraging and reassuring Sophie about the grand opening, as well as grieving together and comforting her about Donna’s death. In Mamma Mia!, they share around 15 minutes and 30 seconds of screen time, and in Mamma Mia! Here We Go Again, they have 16 minutes and 54 seconds. This totals up to 32 minutes and 24 seconds across both films.
 
SCORE: A+ for being there for Sophie when she needed a parental figure the most.
 
Harry:
Harry and Sophie spend most of their time together with other people, but they get small moments to themselves that count for a lot. Harry plays the guitar he bought Donna, and he and Sophie sing together. In the sequel, though he’s not there in the beginning, he abandons his business meeting in order to go to the grand reopening and be there for Sophie. He prioritizes his family time over work, which surely means a lot to Sophie. In Mamma Mia!, Harry and Sophie share 14 minutes and 26 seconds together, while in the sequel they share 12 minutes and 36 seconds together for a total of 27 minutes and 2 seconds.
 
SCORE: A- for prioritizing his family. 
 
Bill:
Bill and Sophie have a similar relationship as her and Harry. They go sailing on Bill’s boat, where he teaches her the basics of sailing. He shares stories of his past with Donna and they have lunch. In the sequel, similar to Harry, he shows up near the end to surprise Sophie instead of accepting an award for the Best Swede. He also saves the grand opening by knowing a sailor, who he saved with Donna 25 years ago, and is able to bring himself, Harry, and Sky back to Kalokairi. Bill and Sophie share around 15 minutes and 15 seconds in the first film and 12 minutes and 36 seconds in the sequel, which adds up to 27 minutes and 51 seconds total. 
 
SCORE: A- for saving the day.
 
DEPENDABILITY
 
Sam:
Sam has already had experience in being a dad, having two grown sons. So, he uses this to help Sophie and give her the support she needs. After their boat day and seeing how good of an artist Sophie is, Sam encourages her to chase a career in it. He sees how bright she is and wants the best for her. When Sophie is working on the hotel, Sam is nothing but supportive and actively helps with the opening. He is Sophie’s rock, someone she can rely on while rebuilding the hotel in Donna’s honor. 
 
SCORE: A.
 
Harry:
Harry says he always wanted a daughter, and when he finds out Sophie may be his, he is enthusiastic. He offers to help Donna pay for the wedding. He wants to be there for her right away, and as previously stated, he is willing to make career sacrifices in order to support her. Harry is all in on being a dad, especially since it’s the only real family he has. 
 
SCORE: A.
 
Bill:
Bill is the first to find out the truth and is initially shocked by the revelation that Sophie may be his daughter. He tries to wrap his head around the fact his great-aunt left Donna the money, which she only ever said was "left for family". It shakes his whole world and his lone wolf lifestyle, but he accepts her with open arms and is accepting of her immediately. In the sequel, as previously stated, he abandons accepting an award in order to be there for Sophie on the day the hotel opens. He remembers that family is all that matters. 
 
SCORE: A.
 
SINGING
 
Sam:
This is not Sam’s strongest category. Pierce Brosnan just cannot sing, this is a fact. He’s a great leading man, but he belts everything, looking like he’s struggling to get the words out. In the sequel, he does better, mainly because he doesn’t have full solo songs and he’s pushed into the background vocals with everyone else. They gave him, someone with little to no musical experience, the hardest song to sing for the male lead. He acknowledges this as a weakness, and we applaud his attempt. 
 
SCORE: C+, but an A for effort.
 
Harry:
Harry was a singer when he was younger, so it’s fitting his voice is good. Colin Firth is able to inject a wonderful and quirky performance into "Our Last Summer" from the first film. It’s his only solo song -- well, not technically since he shares it with Sam and Bill, but it’s a great scene. 

 

SCORE: B for his only “solo” song.

 

Bill:

Bill doesn’t sing much throughout both films. He only has small parts in “Our Last Summer” and “Take a Chance On Me”, and has background vocals in the “Waterloo” credits and “Dancing Queen” in Mamma Mia! Here We Go Again. Stellan Skarsgård, one of our greatest living actors, does a lot of talk-singing, which is fine. It would work fine in karaoke at a bar but would not qualify him for "America’s Got Talent". Though, the Mamma Mia! films (especially the first) really are just an excuse for some of the great actors of our time to get drunk and sing ABBA songs. 

 

SCORE: C+ for his drunk karaoke singing. 

 

So, now that we know their grade for each category of D.A.D.S., let’s average out their grades and see who is the best father to Sophie.

 

Bill Anderson averaged out to a B+ -- not bad, a rough start with a not so great ending.

 

Harry Bright ended with an A- -- pretty average score across the board for a decent D.A.D.S. grade.

 

Finally, our winner is Sam Carmichael with an average grade of an A -- great marks across the board with one stumble at the end.

 

However, all three of them, Bill, Harry and Sam are all great fathers and anyone would be lucky enough to have them as their three dads!
