Mark Ruffalo just found out his ‘Avengers’ costar was in ’13 Going on 30′

At Monday’s Los Angeles premiere of “Avengers: Endgame”, Mark Ruffalo found out that he and fellow Marvel star Brie Larson were both in the 2004 movie “13 Going on 30”.

He was shockingly surprised to find out she was during an interview with Entertainment Tonight.

But it does make sense he didn’t know, they never appeared on screen together. But common, she was one of the six chicks!

Granted it’s has been 15 years since the movie came out, let’s just hope he doesn’t forget they were in the Avengers together.
