Has anybody purchased any films from their childhood for nostalgia reasons?

Big. Still great.

The Goonies and Teen Wolf were both good suggestions!

The Money Pit. Awesome.

Arthur. Incredibly funny and if rumours are true that Russel Brand is playing Arthur in a remake, then I for one will not be seeing it.
 
You know you're getting old when you look at a thread like this and think, wha', they're all fairly recent films :)
 
I bought Teen Wolf with Michael J Fox a while back. It's still a classic. Definately the best film about a teenager who transforms into a wolf and becomes brilliant at basketball I've ever seen. It also had Teen Wolf 2 in the set. I never intend to watch it.
