The technique involved using cameras, and multiple monitors to instant show the performance immediately. This saved time and allowed him to complete most of his films on time and under budget.
The directing continuing and he released “The Ladies Man” and “The Errand Boy” (both in 1961). Fun fact “The Errand Boy” happened to be one of the earliest films about the movie-making biz and a lot of it was shot in the offices at Paramount.
The Workaholic
His first all Lewis film was "The Bellboy" in 1960, which he also starred in. The production took place in the Fontainebleau Hotel in Miami and was produced on a relatively small budget with limited shooting time, but it succeeded anyway.
When Lewis was done with the shooing in the days, he would zip over to the hotel and perform in the evenings.
The Bellboy
Paramount was not happy about financing an almost 'silent movie' since that era was long over, but Lewis wanted to play a mostly mute bellboy. The funding was withdrawn, and so the actor fronted the money from his own pocket, all $950,000 of it.
The film also marked the pioneering method of a video assist system, allowing Lewis the ability to see his actions during scenes and thus perfecting the actor/director balancing act.
Cinderfella
Lewis's film "Cinderfella" took the classic fairytale and turned it on its head. In this movie, in particular, Jerry perfected the combination of zany comic sequences, solid storytelling, and emotion.
In the 1960 film, he played the "enchanting princess" while Anna Maria Alberghetti took on the role of the "charming prince." Needless to say, it was a hit.
The Nutty Professor
In 1963 Lewis co-wrote, directed, and starred in the hit comedy "The Nutty Professor." The film gave a satirical spin on the old classic "Dr. Jekyll and Mr. Hyde." In it, he played the nerdy and awkward professor Julius Kelp who formulates a serum that turns him into a handsome yet arrogant ladies' man.
The film was highly acclaimed and was selected to be in the National Film Registry by the Library of Congress in 2004 due to it being “culturally, historically, or aesthetically significant.” Julius Kelp became a huge part of modern culture and recently even got its own emoji. In "The Simpsons," Professor Frink is a character based on Julius Kelp, and of course, Eddie Murphy starred in the 1996 remake.
