Ahead of the 20th anniversary of their film, 13 Going on 30, Hollywood star Mark Ruffalo has nothing but incredible things to say about co-star Jennifer Garner.
The actor explained what initially brought him to the project and why it was the “wonderful chemistry” he had with Garner, 51, that hooked him.

“It was my first kind of studio film and, I’d been doing pretty small indies up to that point. Gary Winnick, our director, said, ‘I want to do a small indie but in a rom-com studio film,’” he said, adding that Winnick told him he would be opposite the Alias actor.
