In the "Star Wars" universe, co-stars Mark Hamill and Adam Driver operate on opposite sides of the Force.

The duo worked together to locate the pooch belonging to Leos Carax, a director currently working with Driver, 35, on the musical "Annette" in Brussels.

Driver filmed a video pleading with fans to help him find Carax's dog, Javelot. Carax, 58, owned the grandfather and father of Javelot, according to Driver.

"We will put you in the movie," Driver said. "We will give you chocolate, we'll christen your child. We'll do anything as a way of saying thank you."

Driver isn't on social media, but Hamill, 68, is -- and he's got well over 3 million followers.
