Plenty of footage has already been filmed including sequences with The Flying Car, The Spiders in the Forbidden Forest and Gilderoy Lockhart's Defence Against The Dark Arts classes.
But, we're going to have to wait a bit longer this time around - there are no plans to release a trailer for Chamber of Secrets for quite a while.
So when will we see one? Well, Warner Bros. are the only people who know for sure.
But a trailer might be included on the DVD release of Philosopher's Stone on 11 May, or we might even have to wait until the summer.
