Envelope, please: The worst movie title ever
By Mark Caro, Tribune entertainment reporter
When actor-director Anthony Newley approached him with a strange-sounding project in the late 1960s, little did Herman Raucher suspect that he would wind up co-writing a movie that four decades later would be honored as having …
The Worst Movie Title Ever.
Yes, folks, we have a winner — or loser or however you’d characterize a title that was singled out as being more awful than any other in cinematic history.
Worse than To Wong Foo, Thanks for Everything, Julie Newmar (the runner-up).
Worse than Mother, May I Sleep with Danger?
Worse than C.H.U.D.
Ladies and gentleman, we bring you: Can Hieronymus Merkin Ever Forget Mercy Humppe and Find True Happiness?
That is just … wow. I looked it up on IMDb and the title can’t fit on one line. Okay, I’m laughing too hard to write anything else.

Though your post was in reference to the worst movie title ever, it also mentioned Summer of ’42, a remarkable film that I have often thought never got its due. Have you seen it?
Worst title ever hmmm…what about ” Dude, Where’s our Car? ” or I think that’s the title. But what can you expect from anything starring Ashton Kutcher? I also hate film titles with colons because that’s a sure sign that the title is gonna be way too long!
Lol,that one is hard to beat.
