YMMV / A Funny Thing Happened on the Way to the Forum

  • And You Thought It Would Fail: Zero Mostel was very reluctant to do the show, and in fact the song "Comedy Tonight" was originally only added to appease him. And of course it ended up being one of his most famous roles (especially since unlike Fiddler on the Roof, he got to be in the movie).
  • Awesome Moment: Pseudelous ends up water-skiing during the chariot chase at the end.
  • Awesome Music: Bring Me My Bride.
  • Ear Worm: "Comedy Tonight"
  • Genius Bonus: Possibly unintentional, but an exchange added for the film (Lycus' scene with Jon Pertwee) is quite similar to one from Plautus' original play "Pseudolus," where the Lycus equivalent Balio hears someone is looking for a man with a quite unflattering description, and simply replies "It must be me."
  • Harsher in Hindsight:
    • Roy Kinnear has a cameo in the film as a gladiator trainer who's accidentally killed. Two decades later, he really was killed in an accident (falling off a horse) while filming another Richard Lester movie, Return of the Three Musketeers.
    • Buster Keaton's death before the film was released paints a dim picture of how long Erronius has to enjoy his newfound family.
    • In the final reprise of "Comedy Tonight," Senex instead says "A tragedy tonight," implying that he's going to kill his wife. Domina's film actress Patricia Jessel died just two years later at a young age.
  • Hilarious in Hindsight:
    • In the movie anyway. Philia: "3 and 5, I always confuse the two."
    • "Comedy Tonight" promises "baritones and basses." There actually aren't any bass parts in the original show, but then Leon Greene was cast in the film, requiring both his songs to be lowered an octave.
    • In the film's opening scene, Pseudolis becomes completely inconspicuous just by sitting on a bench.
  • Ho Yay: Tons of it between Pseudolus and Hysterium, and also some later in the show between Hysterium and everyone, due to the cross-dressing hijinks.
    • Also Pseudolus and Hysterium sing a reprise of "Lovely," which was originally the young (heterosexual) lovers' falling-in-love song. At first it's just Pseudolus trying to convince Hysterium to go along with the crossdressing thing, but then Hysterium starts really getting into it and the Ho Yay skyrockets from there.
    Hysterium: I'm so lovely
    Pseudolus: Literally lovely
    Both: That the world will never seem the same!
    Pseudolus: You're so lovely
    Both: That the world will never seem the same!
    • The movie takes it even farther by having the two replicate Hero and Philia's Imagine Spot of running romantically through a forest and field together.
  • Jerk Ass Has A Point: Sure, Miles Gloriosus is not exactly a great guy but the only reason he's bothering the protagonists at all is because they're attempting to take the bride he paid for fair and square.
  • They Wasted a Perfectly Good Character: Or rather, actress, as the songs cut from the film mean that Patricia Jessel as Domina only gets to display her magnificent singing voice on three words with her rendition of "something for everyone" in the final song. And she passed away just two years later at age 47 without doing any other musicals, robbing us of hearing what she could do with a bigger singing part.
