Happy Halloween! It’s October 31st and some celebrities are already showing off their Halloween costumes before trick-or-treating time.

SUNY Oswego alumnus Al Roker dressed up as “Beetlejuice” Thursday for the movie-inspired costume theme of the “Today” show, which also featured Dylan Dreyer as Lydia Deetz, Carson Daly as “Austin Powers,” Willie Geist as Ron Burgundy “Anchorman,” “Peter Alexander as “Mrs. Doubtfire,” Craig Melvin as Axel Foley from “Beverly Hills Cop,” and Hoda Kotb and Jenna Bush Hager as Jack and Rose from “Titanic.” Savannah Guthrie also impressed as Elle Woods from “Legally Blonde” with surprise guest Luke Wilson, who reprized his Emmett character from the 2001 film and its sequels.

“Haha, it’s show time!” Roker said as the Michael Keaton character. “Let’s turn on the juice and see what comes out, I’m the ghost with the most!”

Other early favorite celebrity Halloween costumes include Kylie Jenner as ‘Barbarella’, Jennifer Garner as her ’13 Going on 30′ character, Janelle Monae as ‘ET’ and Halle Bailey as multiple Halle Berry characters including ‘Catwoman ‘, bikini-clad Bond girl Jinx from ‘Die Another Day’ and Miss Stone from ‘The Flintstones.’
