What other movies did James star in besides Back to the Future?

He was great as a cop in 'Masters of the Universe'. A life action film based on the He-Man cartoon.

He also pops up every now again when I watch old 80's, early 90's films.

He was also in "Top Gun", and Flux might be interested to know, he was in a movie called "They Might Be Giants" :)

He also had a part as a government agent in Matthew Broderick's "War Games", in a war movie taking place in the Middle East as a colonel (around 1991-1992, can't remember the name though), and a regular role in a short lived series called "Cobra" with martial arts expert Mickael Dudikoff. He played authoritative parts too in those roles, just as he did portraying Mr. Strickland in the BTTF trilogy.
