'Alexander And The Terrible, Horrible, No Good, Very Bad Day': Watch The Trailer Now

Guess who's not having a great day. (It's Alexander.)

It doesn't hit theaters until October 10, but there's no reason we can't start a "Bad Day" early.

That's right, the first look at "Alexander and the Terrible, Horrible, No Good, Very Bad Day" is here. Much like the classic children's book of the same name, written by Judith Viorst, the movie's events center around a kid named Alexander (Ed Oxenbould), who is basically a bummer magnet.

After he has a not-great day and wishes his family understood his woes (updated to include baby's first doctored photo/texting scandal), his family (Steve Carell, Jennifer Garner and more) also feels the pain. Bella Thorne plays Alexander's older brother's girlfriend, and according to the trailer, has an ideal posterior.

Crocodiles, car accidents and a baby drawing all over its face lurk within the trailer, above.
