Warhorse is an action-packed movie about a horse called Joey who's sent to help on the battlefields of World War I.
It's the film version of the children's book by Michael Morpurgo and it's directed by probably the most famous film director in the world - Steven Spielberg.
Joe was at the premiere to meet the stars and here's a review of what he thought of the movie.
When's it out?
It's in cinemas from Friday 13 January - rated 12A.
It's set in 1914, during World War I, when a farm boy called Albert gets a new horse, Joey, who he trains up and becomes best friends with.
But Joey is sold to the British Army and sent to help on battlefields along with millions of other horses.
The story follows Joey's dangerous adventures as he meets loads of people and tries to find his way back to Albert who comes looking for him.
Albert is played by someone who has never been in a movie before, so you won't recognise him.
There are some other stars that you'll know though, like David Thewlis, who plays Remus Lupin in Harry Potter, and Benedict Cumberbatch, who plays Sherlock Holmes in the BBC series Sherlock.
Hit or miss?
Big hit! The horses they use to play Joey and his horse friend Topthorn are amazing and really do act brilliantly alongside their human co-stars.
Movie makers used loads of different horses for the movie and made them all look like Joey and Topthorn so we wouldn't notice - it works really well.
The action is also really good with the battlefields of World War I brought to life on the big screen.
But there are some upsetting scenes so some young Newsrounders might want to wait until they're ready to watch those. If in doubt - ask your parent or guardian what they think.
In the end though everything works out well, and with the music and the brilliant filming you'll feel happy to have watched it.
A big thumbs-up (or should that be hooves up?) from me!
