Mark Ruffalo may be hard at work on the set of Thor: Ragnarok, but that doesn't mean he can't have some fun with the props!

On Monday, the 48-year-old actor posted a funny video of himself goofing off on set… Hulk hands and all.

Ruffalo put on the gigantic green fists as he ran towards the camera, giving a good punch towards the person filming him.

"Hey brothers and sisters, I'm finally on Snapchat taking you on the set of @marvel #Thor3 Follow along ? markruffalo," Ruffalo captioned a pic of him taking a Snap selfie in his makeup trailer.

Ruffalo isn't the only hunky star from Thor: Ragnarok to be sharing his experience with his fans via social media. Chris Hemsworth has also been posting pics while on set in Australia.
