Mark Ruffalo almost couldn't hang with Jennifer Garner, who had been his co-star in the popular film 13 Going On 30. In a widely comical and memorable shot from the film, Matt and Jenna who were 30 and living in the city of New York, were dancing to the tunes of Michael Jackson's Thriller to keep the office party more alive. Recently, Jennifer revealed that that particular scene had been the most difficult time while shooting the film.

"We started to learn the dance. Our first rehearsal, I think it was Mark and Judy and me, and Judy and I were both dancers growing up and poor Mark didn't know that. And he came in and he hated the rehearsal process so much he almost dropped out," Jennifer Garner said in an interaction with a video-based publication.
