Entertainment Movies See Alan Rickman in His Last Movie 'Alice Through the Looking Glass' as Director Pays Tribute: 'He's Exceptional' Alice Through the Looking Glass, marks the last project Rickman worked on before his death By Jodi Guglielmi Jodi Guglielmi Instagram Twitter Writer-Reporter, PEOPLE People Editorial Guidelines Published on February 16, 2016 09:30 AM Share Tweet Pin Email Photo: David Harrison/eyevine/Redux The second trailer for Alice Through the Looking Glass debuted Monday night during the Grammy Awards – and it marked a bittersweet occasion. The film was the final project Alan Rickman worked on before his death. And, in fitting honor of his legacy, the trailer begins with Rickman’s unmistakable voice warning Alice returning to Wonderland. “You’ve been gone too long Alice,” he says. “And do mind your step.” Along with the release of the trailer, Alice Through the Looking Glass director James Bobin has spoken out about working with the actor on his final role. In a touching tribute, Bobin called the Harry Potter star “exceptional.” “It’s a terrible honor to have,” he told Total Film, according to the Independent, of working with Rickman on his last performance. “Obviously he’s exceptional; an incredible voice. As a performer, that’s such a rare thing to have – the moment you open your mouth, to know exactly who that is. But he has that. It lends us gravity.” Though Rickman is primarily known for his role as Severus Snape in Harry Potter and his turn in Love Actually, he also did voice work, including his performance as Absolem the Caterpillar in 2010’s Alice and Wonderland. “Absolem is the wise, mysterious, oblique person that he is in the books,” explained Bobin. “From the first movie, Alan absolutely nailed it. And he really guides you into our movie. It starts with him, and he takes Alice back.” Rickman died on Jan. 14 after a battle with cancer. He was 69. The late actor is also set to appear the upcoming Eye in the Sky, which will have a limited release in the U.S. on March 11. Alice Through the Looking Glass will be released May 27.
