Overdrawn At The Memory Bank. Raul Julia plays a average citizen who decides to take a mini-vacation by downloading his mind into the body of an ape. Complications arise when his memory is 'lost' in the system and he experiences a whole new version of reality.
Between this, Adams Family and Street Fighter, I kinda get the sense that Raul Julia was like Bruce Campbell in that he only took on super fun, and goofy roles in not-so-great movies because he just liked having fun and didn't care about being a big star or making hella money.
Street fighter was for his son who was a fan of the game. Of course, this was also while he was battling cancer and it became his last role. Incredible scene chewery.
