Michael Keaton on Playing Ken in 'Toy Story 3' (VIDEO)

Michael Keaton, who provides the voice for Ken in 'Toy Story 3,' talks about wearing the Ken doll's outfit in real life and riffs on a lesser-known doll called "Jihad Ken" on 'Good Morning America' (weekdays, 7AM ET on ABC).

Keaton jokes that, as a method actor, he's worn Ken's short shorts and ascot in real life to get into character. Then, Keaton muses on the success of Ken, noting that some versions of the doll were probably more popular than others.

"There are many, many, many Ken dolls ... And some probably sold better than others. I would say, probably, 'Jihad Ken' didn't sell," Keaton said.
