Ruby Gillman, Teenage Kraken Second Trailer Surfaces

Under the sea is a popular setting for animated films. From classics like Disney's The Little Mermaid, Ponyo and Finding Nemo to lesser known movies like Help I'm A Fish, there are plenty of stories to be told. Dreamworks Animation is headed beneath the waves for the first time since 2004's Shark Tale in their new feature Ruby Gillman, Teenage Kraken.

Ruby is a normal, shy 16-year-old girl- who just happens to be descended from a long line of warrior queen Krakens. Desperate to fit in at Oceanside High, all she really feels is invisible. She's maths tutoring her crush, skater boy Connor, but he barely seems to know she's alive. And she's prevented from hanging out with the cool kids by her overprotective mum's forbidding of her ever going in the water.

When she breaks her mum's number one rule, Ruby discovers that is her destiny to inherit the throne from her formidable grandmother The Warrior Queen Of The Seven Seas.

The Kraken are sworn to protect the Oceans from their ancient enemies- the vain, power hungry mermaids. The only problem is that Chelsea, the popular new girl at Oceanside, just happens to be a mermaid.

Ruby Gillman, Teenage Kraken is directed by Kirk DeMicco, and co-directed by Faryn Pearl. It's written by Pam Brady,  Brian C Brown and Elliott DiGuiseppi. It's produced by Kelly Cooney Cilella, co-produced by Rachel Zusser and executive produced by Mike Mitchell.

Lana Condor stars as Ruby, with Toni Collette as her mum and the legendary Jane Fonda as the Warrior Queen. It also stars Colman Domingo as her father, Sam Richardson as her uncle and Blue Chapman as her little brother, It also features the voices of Will Forte, Nicole Byer, Liza Koshy, Ramona Young, Eduardo Franco, Echo Kellum and Emma Chamberlain.

The second trailer shows us the film's mixing of High School antics and Kraken action. We see Ruby struggle to balance the usual challenges of teenage life and her new existence as a giant Kraken. We also see what look to be pretty spectacular Kaiju-style smackdowns of Krakens taking on mermaids.

Ruby Gilman, Teenage Kraken arrives in cinemas on June 30.
