Movie Title Game: Before & After

A space-time vortex sucks a scientist and his assistant Holly into a world populated by dinosaurs, and a young mechanic is drawn into a web of deceit by a temptress who is cheating on her gangster boyfriend.

Three years after a prank went terribly awry, the college students responsible are targeted by a masked killer aboard a moving train, and a zombie virus outbreak on another train, leaves passengers struggling to survive.

One of these titles was a hilariously offensive National Lampoon special aired on HBO in the late 1970s. It's reputed to be the lowest rated program in HBO history. If you didn't see it then you've probably never heard of it, but I rather doubt the "lowest rated" reputation -- if you were a college student in the years soon after, you likely knew someone who had a VHS tape of the program.

When retired engineer Frank Corvin is called upon to rescue a failing satellite, he insists on being accompanied into space by his equally old teammates, an extraterrestrial beaver and the gay vampire Dragula, but they endure numerous interruptions including a woman with a Perrier addiction who performs the song, "Roger Me, Roger" and contestants competing in a game show called "The Breast Game." Stars Sarah Durkee as New Orleans businessman "Clay Shaw."

EDIT: It's been a full day now with no response, so I'm adding the answer below.

The two titles are:

Disco Beaver from Outer Space (1979)
Space Cowboys (2000)

And so ... Disco Beaver From Outer Space Cowboys.

The before/after part here isn't a word, but a syllable ... well, sort of.

Supervillians Roger, Pete, John, and Keith and a collection of nutty cons at Belle Reve prison join the super-secret, super-shady Task Force X, but loathing their jobs and parents, they seek solace with their mod clique, scooter riding, and drugs, only to be disappointed. Stars Margot Robbie and Idris Elba as "Doctor Jimmy" and "Mister Jim."

EDIT: It's been a full day now with no response, so I'm adding the answer below.

The two titles are:

The Suicide Squad (2021)
Quadrophenia (1979)

So ... The Suicide Squadrophenia.
