Beast Mode goes Hollywood!!
Marshawn Lynch was front and center at the L.A. premiere of "Westworld" on Thursday night ... leaving many asking the question -- why??
Turns out, HE'S ON THE SHOW!!
The Seattle Seahawks legend plays a tough guy (shocker) on Season 3 of the HBO sci-fi series ... you can even see him in the trailer, standing next to Aaron Paul and Lena Waithe.
The crew had a blast at the TCL Chinese Theatre in Hollywood for the big premiere while hanging out with the star of the show, Thandie Newton.
