Steven Segal --- On Deadly Ground
Y.K. Kim - Miami Connection (1987) 😄
Sure he was terrible but he didn't direct it.
Tommy Wiseau: The Room Any Neil Breen film.
Tommy is so bad at everything: writing, directing, acting, probably even breathing.
Quentin Tarantino - Django Unchained (2012)
He's terrible in his own movies but decent in other peoples. I liked his role in From Dusk Til Dawn.
