14 of Mark Ruffalo's Best Movies Through the Years

One of Ruffalo's latest roles reunites him with his "13 Going on 30" costar Jennifer Garner, who plays the parents of Adam (Walker Scobell), a boy who is thrown into a journey with his older self (played by Ryan Reynolds). Louis, Ruffalo's character, dies when Adam is very young and, now, both Adams are on a mission to save the future — one that requires them to go back in time and work with Louis.
