Newsround's Sonali used to street dance so she jumped at the chance to review this film.
21 May, rating PG
The face you'll recognise the most is George Sampson - his role as a wannabe dancer was especially written for him. Dance group Flawless play The Surge - the bitter rivals to Carly's crew. And look out for a performance from Diversity.
Carly and her boyfriend Jay have reached the finals of the UK Street Dance Championships with their dance crew. But Jay walks out - leaving Carly struggling to lead the crew.
A ballet scene from StreetDance
Ballet schoolmistress Helena comes to the rescue - she's impressed with Carly's enthusiasm and offers a deal - the crew can practise in the Ballet Academy's dance studio in return for including her ballet dancers.
The two very different dance styles face off against each other - can they find a way to work together before the Street Dance Championship finals?
The dance-offs are definitely the highlight of the film.
Sonali watching the film in 3D
I was expecting Diversity to have a bigger role, but you see a lot more of Flawless, who are brilliant. It's also funny to see how bad the ballet dancers are at street dancing at first.
The music is also one of the best bits of the film with N Dubz, Pixie Lott and Cheryl Cole all on the soundtrack. They've used Madcon's Beggin really well at the start of the film and Pass Out by Tinie Tempah makes you want to get up and dance in the club scenes.
The film is in 3D - in fact, it's the world's first 3D dance movie. It means some of the dancing pops out at you, but you do forget it's in 3D in parts of the film. The 3D shots did make London (my favourite city in the world!) look amazing.
I also quite liked Carly's outfits.
I think the best character in the film is Eddie, which is played by George Sampson. It's his first movie, but you couldn't tell because his acting is great.
He's really cheeky and is desperate to dance in Carly's crew, but she keeps saying no. But don't worry - you get to see him doing what he does best towards the end!
Any weak bits?
We've seen the storyline loads of times before in movies like Step Up and Step up 2: The Streets, so the plot doesn't feel original. Some of the lines were a bit cheesy and some of the acting could be better.
Hit or miss?
A hit if you love to dance or at least like to watch other people dance to some great music. Otherwise, give it a miss.

Rebecca, 11, Lancashire, England
"This film is really good! The dancing was amazing and I loved the plot! The outfits were really cool but the only thing I didn't like was the 3D. It wasn't very good, it would have been better in 2D. I'd give it 4/5."
