Ex-Seahawks star Walter Thurmond III is trading his football helmet for a movie producers chair … telling TMZ Sports he’s already involved in 3 feature films and a documentary.
Thurmond -- who's only 28 -- retired last week after 6 very successful, but injury-plagued seasons in the NFL ... leaving many fans shocked.
"I am completely done with professional football," Thurmond tells us, "It's time for me to pursue other passions."
Those passions ... producing and directing movies. Among the projects ... a music documentary (about Eddie Levert of the O'Jays) and a feature horror film.
