The Fly (1986)

Still creepy and disgusting. The Fly feels almost like a three-person play, or a Twilight Zone episode. The Fly is a brisk 96 minutes, and could have been even shorter without the love-triangle machinations which aren't totally necessary.
The cast list includes only 10 speaking parts: Seth Brundle (Jeff Goldblum), Ronnie (Geena Davis), the "other man" Stathis Borans (John Getz), a bar tramp that Brundle tries to trick into teleporting (Joy Boushel), and six bit parts.
Real life couple Geena Davis and Jeff Goldblum have terrific chemistry, and they both exude an egghead intellect that powers the movie.
Of course the science behind the telepods is nonsense, but The Fly stands as a cautionary tale for what can go wrong when a single person designs software and conducts experiments with no oversight or testing. If only he'd programmed his computer to NOT fuse two organisms together! The makeup effects are mostly solid, it's the idea of the fly emerging from Brundle that makes this movie a success.

I laughed out loud when I saw this outfit, even though Davis was delivering
the trademark line "Be Afraid. Be Very Afraid."

Note: Where did they get these bizarre character names? Seth Brundle, Veronica Quaife, and Stathis Borans?
Eighties Test: The Fly mostly passes the timelessness test- the telepods still look great; the computer is housed in a giant casing like a supercomputer, and the UI looks terrific. One of Ronnie's costumes - the one she's wearing when she says "Be afraid. Be very afraid" is so Eighties I almost laughed out loud. Besides her hilarious lapels, the festive scarf does not fit the occasion. (On Demand)
