I completely misinterpreted the title.

I thought "Real Genius" and "Film Nerd" was referring to "Val Kilmer", like it was saying "RIP Val Kilmer, a real genius and film nerd that culture deserves" instead of "RIP Val Kilmer, who worked at Real Genius, the film that nerd culture deserves".

I must say that I never heard about this movie and I'm happy that this is a recommendation of a 80s movie
