\"I think it's always important for me to try to break the scene and laugh as much as possible,\" Moretz said.

Without giving anything away, the actress said, \"There is an appendage lost during filming, and we found it very funny to hide it in areas and put it in food and put it in coffee cups.\"

Moretz, who was just 5-years-old when she was in \"Amityville Horror,\" told \"GMA\" she didn't see the full movie until she was older.

\"My mom was strict on me not being allowed to watch that, so we would fast forward through the scary parts,\" Moretz said. She watched her own parts, \"But all the really gnarly stuff that happened, I didn't get to see till I was older.\"

The young actress recently celebrated her 22nd birthday with an early 2000s themed bash and mirrored her look after an \"iconic\" pop-star.

\"I dressed up like Britney Spears in a denim-on-denim dress, which was absolutely ridiculous,\" she said. \"Late '90s, early 2000s was such an iconic period for a lot of crazy fashion looks.\"

\"Greta\" hits theaters on Feb. 28.
