Mark Ruffalo Almost Quit '13 Going on 30', Jennifer Garner Says

Jennifer Garner is spilling a new tidbit about 13 Going on 30.

The 48-year-old actress was reminiscing about the rom com when she revealed that Mark Ruffalo, who played Matty, almost quit over the iconic “Thriller” dance scene.

During her interview on theSkimm’s “Texting With” digital series, Jennifer spilled the set secret.

“We started to learn the dance,” Jennifer recalled said, referring to her and co-stars Mark and Judy Greer. “Our first rehearsal I think it was like Mark, Judy, and me, and Judy and I were both dancers growing up, and poor Mark didn’t know that.”

Jennifer remembered him coming “in and he hated the rehearsal process so much he almost dropped out of the movie.”

However, Mark stuck things out and the dance scene is one of the most memorable in the movie.

Earlier this month, Jennifer opened up about reuniting with Mark for The Adam Project, calling the experience “wonderful”.

When they first reunited on the set, Mark even gave a sweet nod to 13 Going on 30. Check it out!
