Giant Movies That You Never Hear About Anymore

Not sure if it would qualify as "Blockbuster" but all those Pauly Shore movies in the early 90s - Encino Man, Son-In-Law, Class Act, etc.

Also in the late 80s, there was this Australian guy named Yahoo Serious. He made this movie called Young Einstein, who seemed to be all over MTV for a period of time, then the Berlin wall fell and he dropped off the face of the Earth.
