Wait, in 1976, there was a film called "Alice in Wonderland" directed by Gene Wilder. He co-wrote and starred in it with Jerry Lewis as the Mad Hatter. But Wilder's Alice was for all ages, not X-rated. So that's not it. Then there's the 1976 version directed by Martin Rosen, which is an animated film, again family-friendly. So perhaps the user is referring to a different version.
