Colin Farrell visits an aquarium with Lily Cole

Colin Farrell and Lily Cole take a break from filming to visit an aquarium in Canada.

The Irish actor and the London born model were spotted visiting Vancouver Aquarium as they took a day off from shooting the 'Imaginarium of Doctor Parnassus.'

Lily, 19, was spotted with a bag full of toys, while Farrell, 31, preferred to keep a low profile, ducking his head in front of the cameras.

The Terry Gilliam production originally starred the late Heath Ledger but was halted when he tragically died on 22 January.

It has been reported that Terry Gilliam will use three actors to fill the void left behind by Ledger, who was midway through making the movie before his death.

The $30 million fantasy film is believed to involve a supernatural mirror that takes people into different dimensions. This has allowed Gilliam to use three big names to play different incarnations of Ledger's character.

According to Jude Law's spokeswoman, Law and Johnny Depp are the other names that will finish off Ledger's work.

Farrell has said it's a hard decision to complete what Ledger had created, but said he would be, "honored to be part of it."

"It makes me feel uncomfortable to think about it too much and get into it really here but it's an incredibly painful honour to have, you know, and an honor I wish I wasn't bestowed but an honour none-the less," Farrell told an Australian newspaper.
