Parts of that movie still give me the creeps when I watch it.Event Horizon
I've seen the movie a few times by now and, I must admit, on first viewing I was a bit put off by it but subsequent viewings were more enjoyable. The various debates both before & after her journey are really what defines the film.Contact, the 1997 film from Carl Sagan's 1985 book.
A serious and adult treatment of how the first contact with an alien race might go. Absolutely brilliant - one of the best SF films I've seen, and Jodie Foster deserved an Oscar for it.
