After "Mork and Mindy," Robin Williams became a hot Hollywood commodity and was able to retired from doing sketch comedy shows altogether. Instead, he made hit movie after hit movie, starting with 1980's "Popeye" based on the famous cartoon character of the same name. After that, a string of films followed, including "The World According to Garp," "Good Morning, Vietnam," "Hook," "Mrs. Doubtfire," and "Dead Poet's Society" (via IMDb).

And while you'd think his rates would continuously rise after being in such high demand, he humbly accepted a mere $75,000 to voice the Genie in Disney's 1992 "Aladdin." According to Celebrity Net Worth, although he didn't want to be used in any merchandising and didn't want to be in more than a quarter of the film, Disney broke that agreement and he refused to work with them for years the followed and only did so "only after the executive in charge had been dismissed."

As one of the most recognized names in movies at the time, Williams' value increased considerably when he became an Oscar winner in 1997 for "Good Will Hunting" (via Biography). So much so that in 1999, he was able to command his highest salary for a film – $20 million for "Bicentennial Man."
