Two of Australia’s favourite stars have joined Tinseltown’s elite voicing the characters of ‘Mark’ and ‘Keith’ two hapless guinea pigs in the Australian version of the upcoming animated action-adventure film, joining Dwayne Johnson, Kevin Hart, Kate McKinnon, John Krasinski and Keanu Reeves.

In “DC League of Super-Pets”, Krypto the Super-Dog and Superman are inseparable best friends, sharing the same superpowers and fighting crime in Metropolis side by side. When Superman and the rest of the Justice League are kidnapped, Krypto must convince a rag-tag shelter pack – Ace the hound, PB the potbellied pig, Merton the turtle and Chip the squirrel – to master their own newfound powers and help him rescue the superheroes.

No superhero story is possible without a nemesis or two, so the film’s roster of villains includes Lulu the telekinetic guinea pig, hell bent on exacting her own brand of justice. An all-powerful evil genius with an army of mutant guinea pigs, who better than Australia’s favorite vet Dr Chris Brown and comedy queen Julia Morris to give voice to the fluffy, fiery furballs of fire and ice.

A somewhat reluctant duo at times, Mark – voiced by Brown – is a flying, flaming fire-breather while Keith – voiced by Morris – is a frozen rodent with ice in their veins. Together, they help Lulu carry out her sinister plot to kidnap the Justice League and fight the Super-Pets, reaping mayhem across Metropolis.

From Dr Chris Brown:

It’s a bit of a dream to be involved in a DC film. And as someone who already gives voices to just about every animal they meet, playing the role of a guinea pig with superpowers feels a lot more normal than it probably should!

Julia Morris said:

Well, I’ve been described as super and been described as a pet but never in the same sentence. I could not be more thrilled to be part of this global extravaganza! How completely exciting to do it alongside my beloved Dr. Arm in arm or paw in paw.
