Maybe this doesn't count as a rip-off as both were made by the same guy but Jamie Uys' The Gods Must Be Crazy is a rip-off / remake of his first film Daar Doer In Die Bosveld [Far Away In The Bushveld, 1951] 

[hellbilly]

Night Visitor (1989) and Never Cry Werewolf (2008) both rip off Fright Night (1985), as in same plot and set up, same characters (with different names of course) and even same scenes.

Population 436 (2006) (good movie btw) rips off The Wicker Man (1973).

Paranormal Activity (2007) rips off The Blair Witch Project (1999).

The Orphanage (2007) rips off The Others (2001).

The train-station scene from The Untouchables is supposedly a rip-off of the 1925 silent film Battleship Potemkin. I've never seen the film, but a friend of mine who was a film student told me that if you watch the scene from Battleship Potemkin it is pretty obvious. I personally don't care too much, I think the scene in The Untouchables was well done and I've always liked the film overall. However, this would be one of those things where, if De Palma did rip it off, how many filmgoers would know of a silent film from 1925 anyway? Hollywood has done this many times: utilize the ignorance of the typical American moviegoer by exploiting the work of brilliant but obscure filmmakers from the past.

Anaconda (and any other film featuring a real life water monster) is a rip off of JAWS
