Carrey grabbed co-star Meryl Streep and danced with her around Leicester Square, which had been decorated in yellow and lemon trees in honor of the movie, the Daily Mail reported Sunday.
The dark comic story is about three orphaned children whose parents die in a fire. They are taken in by their wicked uncle Count Olaf, played by Carrey, who tries to get his hands on their fortune.
"Mums and dads, if you value your values you really should stay away," joked Carrey, who added that the film is darker than a traditional fairytale.
