Games are safe, movies SHOULD be safe (and if they're not, that's rediculous). As for save game files, if you had PS+ and backed them up to the cloud then you should be good, but the only other way to get them back is to pull out the hard drive and put it in another PS3.
EDIT: Ok, swapping hard drives might not be as simple as I thought. You might want to ask others about that.
