Los Angeles, Jan 31 (IANS): Actor Ryan Reynolds has shared a few pictures along with actor Mark Ruffalo from the sets of The Adam Project but it is the funny caption that catches the eye.

On Instagram, Ryan posted three pictures from the sets of The Adam Project, a science fiction film directed by Shawn Levy. For the caption, Reynolds gave a hilarious reference about superhero Hulk, played by Ruffalo in the popular "Avengers" franchise.

"I have a friend from work too. But no matter how angry I make him, he stays the same size. @markruffalo #TheAdamProject," Reynolds captioned the image.
