Gronk got another movie role!!!
Rob Gronkowski grabbed his badge and his gun to play a cop for the new flick, "You Can't Have It" -- which stars Joanna Krupa and Armand Assante.
Unclear what the movie's about -- but Rob ain't the only Gronk with a role ... his brother Dan Gronkowski also plays a cop.
It's a big move for Gronk who previously told us he's into the Hollywood scene -- and at the very least, he's flirting with the idea of becoming a movie star after his playing days are over.
