Simon Pegg turned to father-in-law to perfect his Scottish Scotty

Funnyman Simon Pegg perfected his Scottish accent for the Star Trek films with a little help from his Glaswegian father-in-law.

The Brit plays Montgomery Scott, aka Scotty, in the new Star Trek movie franchise and, in order to perfect his dialect for the role, he turned to a familial source - his wife's dad.

He says, "One half of my family is Scottish, so I based it on my father-in-law, who is a proper Glaswegian... He's very proud of it.

"He tries to make me put things into Star Trek. He gives me words to say... I tried to get in 'Ya wee scunner' and... 'Get down the cludgy,' which is the toilet, but (director) J.J. Abrams will come up to me during shooting and say, 'Simon, we have to understand what you're saying,' and I have to rein it in a little bit."
