I Reccentley watched "Spirited Away" and "The Girl Who Leapt Through Time" both of which i thought were ace, so can anyone reccomend another good one for me to watch?

movies eh? Let's see:

Nausicaa and the Valley of the Wind (classic, love it)

Grave of the Fireflies (so very sad)

Princess Mononoke

Jin Roh: The wolf brigade

any movie by Hayao Miyazaki

This.  Oh, and aside from his, you could check out 5 Centimeters per Second.

Steam Boy is pretty good

The Girl Who Leapt Through Time was excellent good taste! However I never understood Princess Mononoke or Spirited Away I thought both movies were nothing special.

I recommend Kara no Kyoukai 1: Fukan Fuukei There are 5 in the series very good.
Also the upcomign Symphonic Poem Eureka seveN: Pocket Full of Rainbows will be amazing.

Princess Mononoke hands down.

Also, check out Castle in the Sky, Howl's Moving Castle, and Nausicaa: Valley of the Wind.

Toki wo kakeru shoujo is one of my favorite anime films. 

If you enjoyed that one, I would recomend Neko no Ongaeshi.

No one mentioning Akira? I know is old, but it still holds up.
