Resident Alien (1991)

A comedy that pays tribute to the science fiction genre -- specifically, the sub-genre of time travel. But here the alternate reality is contemporary New York City where past and future experiences of trust, commitment and denial are cleverly put to the test. Just as Ruby is beginning to relish her first-ever healthy relationship, Sam begins muttering about being a time traveler from the year 2470.

In 1970s London, a teenage outsider named Enn falls in love with a rebellious alien girl named Zan, who has come to Earth for a party. Together, they navigate the complexities of intergalactic culture and the trials of first love.

Set against the backdrop of a postapocalyptic Earth whose Eastern Hemisphere was destroyed by a massive solar flare, leaving what life remains mutated from radiation and fallout.

David Hyde Pierce, playing an alien (credited as infinity-cubed in the opening credits), narrates a courtship in a late-20th century American city as an extraterrestrial nature documentary. The relationship "footage" is played straight, while the voice-over (with its most often wildly inaccurate theories) and elaborate visual metaphors add comedy.

Aspiring composer Jim Sanders is engaged to spoiled rich girl Patty. But the morning after his bachelor party, Jim wakes up to discover a beautiful, broken-winged angel in his pool. When everyone finds out about his heavenly houseguest, Jim must cope with a dangerously jealous fiancée, an exploitive future father-in-law and a group of buddies with an outrageous business plan!

A wildly inventive deconstruction of the romantic comedy built around the question: What would you do if you could travel to your loved ones’ past, heal their traumas, fix their problems, and change them into the perfect partner?
