I realize IMDb shows Lou Diamond Phillips' first movie as Time Bomb (1984), but I distinctly remember watching a Christian movie at church as a young teen (early 80's), with him in it. Then when La Bamba came out, I was like: "Hey, that's the same guy!"
I grew up in a super conservative church in which secular movies were not allowed; so being able to watch a movie/video at church was a big deal, even though it was a Christian-based movie. I think this may have been the first "movie" I had ever seen besides TV. I don't remember anything about the movie except that it took place in western US during modern times (think old-gas-station-in-dusty-west type of movie).
Did he get his start in Christian movies, or am I going nuts? It was a long time ago.
