Comedy Film Titles As AI Image Prompts

I tried to get Midjourney to create modern posters for classic comedy films.  I provided plot summaries, listed the names of the lead actors, and sometimes provided reference photos.  The results were not good.  

So, I changed course.  Instead, I submitted the film titles as prompts with no other information.  What images would these titles inspire?  Many of the titles have no significance by themselves.  A person who is unaware of the Marx Brothers would have no clue what A Night at The Opera was about.  They would not think about dozens of people crowding into a tiny stateroom.  They would not think about Groucho's witty one-liners, Chico's charming malapropisms, or Harpo's mischievous antics.  They would think about an evening performance at an opera house.  But, regardless of nondescript prompts, Midjourney was still able to produce imaginative images.  Midjourney surprised me in that it was aware of post-1970 comedy films and gave me images specifically related to those films.  Let's see how the program generally did with this exercise.
