Chris Pratt posted on Instagram a photo of him with his brother Cully and 5-year-old son Jack after a screening of the latest Marvel movie.

"HOLY CRAP!! THOR RAGNAROK IS ABSOLUTELY AMAZING!!! We just laughed our asses off!!! So proud to be part of the Marvel universe," the "Guardians of the Galaxy" star captioned the image of him and his family members offering their best Thor poses in front of a showcase displaying costumes from the superhero movie.

E! News said this is Pratt's first Instagram post since he and his wife, actress Anna Faris, announced three months ago they are splitting up after eight years of marriage.
