Yes, it's true. On March 30, 1992, the Academy Awards were all about The Silence of the Lambs. Based on Thomas Harris' bestselling novel of the same name, The Silence of the Lambs became only the third film ever to sweep all 5 major Academy Award categories(the other two being 1934's It Happened One Night and 1975's One Flew Over the Cuckoo's Nest). The Silence of the Lambs is also the first(and so far only)Best Picture winner to be widely considered a "horror" movie.

In addition to Best Picture, The Silence of the Lambs also picked up awards for Best Adapted Screenplay(Ted Tally), Best Director(Jonathan Demme), Best Actress(Jodie Foster) and Best Actor(Anthony Hopkins as, who else? Dr. Hannibal Lecter):

Yes, March 30, 1992 was a special night at the Academy Awards if you were indeed a fan of The Silence of the Lambs(which I definitely was). By the way, if you love all things Hannibal the Cannibal and you've never seen the 1986 movie, Manhunter, I highly recommend it. It's based on Thomas Harris's novel, Red Dragon, and in my opinion it's much better than the later film adaptation(2002's Red Dragon). It stars William Petersen as FBI profiler Will Graham and Brian Cox as Hannibal Lecktor(notice the different spelling). Cox brings a different(but no less interesting) interpretation to the role of Hannibal. It was directed by Michael(Miami Vice, Heat, Collateral) Mann and it's truly a grade A thrill-ride.
