    My Stepmother Is An Alien (1989) John Lovitz is hysterical as Uncle Ron in this movie who owns a sweet-ass beach house with GLASS BLOCK EVERYWHERE, drives a Rolls Royce and gets ass like it’s nobody’s business.

    The second movie I went to was The Land Before Time, and we had another long wait because they were having technical difficulties. Finally, after an eternity (in 6 year old time anyway) the movie started playing and it was...My Stepmother Is An Alien. They accidentally put on the wrong movie.

    Clinton loved movies. Obama loved movies. GHWBush went to “My Stepmother is an Alien” after the election because he thought entertainment press would give him more exposure. Democratic presidents are cooler. 😎 (And where the Sack Charles once stood is holy ground to Boston movie fans.)

    Said to a friend that I disliked Poor Things because "I didn't like it any more when it was Ex Machina," and I now realize that was wrong of me. I should've said "I didn't like it any more when it was the 1992 Dan Ackroyd/Kim Basinger film My Stepmother Is An Alien"

    Tax purposes movies: Mars Needs Women (1968) for tax purposes; Earth Girls Are Easy (1988) for tax pruposes; My Stepmother Is an Alien (1988) for tax purposes... These 3 would also make an excellent - not politically correct - movie triple feature !!!

    Just watched My Stepmother is an Alien. I appreciate a good, silly, kind of bad movie. Sometimes I forget how strange the 80s were. The past really is a foreign country. Which makes this a foreign film, I suppose. Sounds very high-brow when you frame it like that.

    Weird 80’s comedy in the silly mold of “Earth Girls are Easy” and “Coneheads” A low-paid widowed scientist (Dan Aykroyd) makes contact with aliens and they send an agent (Kim Basinger) to meet him. She has a one-eyed serpentine counselor in her purse and ends up marrying the physicist, even though the counselor’s intention is to destroy the planet (!). Alyson Hannigan plays the winsome daughter while Jon Lovitz is on hand as the researcher’s annoying brother. “My Stepmother Is an Alien” (1988)…
