Off the top of my head :

Lost in Translation

Princess Mononoke

The Fifth Element

Cloverfield

Star Wars (The first one ,episode 4? the original version )

Galaxy Quest

Aliens ( The second one , marines in space )

Alien (The first one )

Bladerunner

Ghost in the Shell ( The first one )

Yipes I forgot Ralph Baski's Wizards and I didn't pick a Harry Potter film either .

Wizards!! I love that one. Most people don't know about it. Great choice.

My 10 are;

Harry Potter - number 3 (love a strong Hermione,whomping willow, and time travel)

Aliens - number 1

T2 - Linda Hamilton rocked

War of the Worlds - original

Star Wars number 4

The Day the Earth Stood Still

Close Encounters

When Worlds Collide

Blade Runner

Wizards

I am sure I could add more. :)

adbastille14 ,

Yeah , Wizards may be Baski's best film but it's far from his most famous .

Hamilton was awesome in T-2 , great selection . Really nice list . I should have considered Close Encounters .

Prince of space and after that nothing comes close except maybe green slime

What comes to mind:

Wings of Desire

Solyaris

Cronos--1993 Spanish version

Carnival of Souls

Night of the Living Dead--the original

Blade Runner

Lord of the Ring trilogy

Harry Potter series

The Haunting--1963 version

Fail-Safe

And there are so many more...

These are both MST3k episodes .I'd missed Prince of Space . Thanks Charker .I remember Starman who was also known as Super Giant . Super Giant was the inspiration for Prince of Space . Have you seen it ? BTW all these films are appealingly awful .

I hadn't heard of Wings of Desire . I just looked it up and it is now on my to see list . Thanks Angharad .

I so wanted to see Solaris ( the remake of Solyaris ) but Clooney said at every press appearance that it wasn't really a SF movie because it wasn't stupid . I understand what he meant but I couldn't bring myself to support him with my money .On your recommendation I'll look for the original .
