Mark Ruffalo is a wonderfully versatile actor. He's made a lot of money portraying the Hulk in the Marvel movies - and enjoyed a lot more success than his predecessors Eric Bana and Edward Norton in the role - but he can play twitchy ad delicate as well as he can play strong and aggressive. If you want evidence of that, all you need to do is look up his riveting work in 'Spotlight'; a movie that will haunt you long after the credits have rolled. We think Ruffalo doesn't get enough credit for his range as an actor.
He's getting hard done by with this gender swap process, too! The process is only supposed to turn men into women and vice versa, but the female Ruffalo looks to have shed somewhere between ten and twenty years in the process! Ruffalo is in his early 50s, but his female counterpart could easily pass for a 25-year-old.
