NFL's Clay Matthews Reenacts Famous Movie Lines

And the Academy Award goes to ... someone other than Clay Matthews.

But hey, at least when it comes to reenacting scenes from classic movies ... the Packers star gets an A for effort.

TMZ Sports put Matthews on the spot at an event for Courtyard Marriott ... and asked him to give us his best shot at some famous lines from "Braveheart" and "Any Given Sunday." After all, he DID have a cameo in "Pitch Perfect 2."

Check out the clip ... Matthews claims he hasn't taken any acting lessons, but we're calling BS. With a little more practice, this guy just might be the next big athlete-turned-actor.

Also, the former USC Trojan gives us his take on his alma mater's recent struggles and explains what the team needs to do to return to greatness.
