WATCH: The Trailer for Bella Thorne's New Movie Is Here!

Bella Thorne in Alexander and the Terrible, Horrible, No Good, Very Bad Day

The trailer for Bella Thorne's new movie is here, and the family comedy will have you falling out of your chair laughing. 

Alexander and the Terrible, Horrible, No Good, Very Bad Day is based upon the extremely popular children's book of the same name, and it centers on awkward preteen Alexander -- and his worst day, EVER. He wakes up with gum in his hair, and things just take a downhill turn from there.

Unfortunately, it turns out that bad luck is contagious, and his cool and collected family isn't immune to the bug. His composed parents, played by Steve Carell and Jennifer Garner, and older siblings are next in line -- and hilarity ensues as they try to make it out alive from the worst bout of bad luck in history. 

The trailer shows off the film's impressive star power, including Thorne as the older brother's girlfriend, Donald Glover (aka Childish Gambino) as Carell's young, cool boss, and Jennifer Coolidge as a DMV instructor. To top it off, the movie is directed by Puerto Rican filmmaker Miguel Arteta. 

Watch the trailer below and let us know: will you be taking your kids to see this movie? It hits theaters October 10, 2014!
