The Amazing Spider-Man star Andrew Garfield donned his superhero suit to surprise kids at a children's charity in London on Wednesday (09Apr14).

The actor delighted youngsters at Kid City, an after-school organization for children aged three to 11, as he wore his onscreen alter ego's iconic blue and red suit to meet his fans.

Garfield crashed their pizza party and later took to the basketball court for a friendly game in his Spidey suit with the eager kids.

He eventually shed the costume to sit down with his young audience, happily posing for photos and chatting with the starstruck devotees.

Later that night, he pulled off another surprise by making a cameo for The Punchdrunk theater company's production of interactive play The Drowned Man.
