The image shows Pratt with his five-year-old son Jack and brother Cully Pratt after they’ve just seen the new Thor film:
“Holy crap!! Thor Ragnarok is absolutely amazing!!! We just laughed our asses off!!! So proud to be part of the Marvel universe,” Pratt captioned the photo.
Pratt plays Star-Lord in another Marvel film, Guardians of the Galaxy.
He and Anna Faris announced that they plan to co-parent Jack despite their separation. “Our son has two parents who love him very much and for his sake we want to keep this situation as private as possible moving forward,” Pratt wrote on Facebook.
