Hear Alan Rickman's voice in "Alice Through the Looking Glass" trailer

Though Alan Rickman died in January, viewers can still remember him and his wonderful voice when they see the new teaser for "Alice through the Looking Glass."

The movie, which is the sequel to "Alice in Wonderland," features most of the original cast, including Mia Wasikowska as Alice, Johnny Depp as the Mad Hatter, Helena Bonham Carter as the Red Queen, Anne Hathaway as the White Queen and of course, Alan Rickman as the Blue Caterpillar.

Rickman narrates the new trailer and though you won't see his face in the film, his voice is nearly just as recognizable in one of the actor's last films.
