It was a bittersweet moment for Lily Cole and the cast of The Imaginarium of Doctor Parnassus this week as they launched the fantasy flick in Cannes without their leading man Heath Ledger.

Catwalk beauty Lily – the image of a fairytale princess in a pale blue Chanel couture gown – said going back to work on the film after Heath's untimely death was difficult. However: "It was the love and understanding between the cast and crew about why we were doing it that carried us through and helped us to complete it."

The Aussie star was almost half way through lensing the fantasy flick - which tells the tale of a travelling theatre troupe who have made a pact with the devil – before he died. Johnny Depp, Jude Law and Colin Farrell stepped in complete Heath's role, with all three donating their wages to the late star's daughter Matilda.

Lily joined co-stars including Austin Powers actor Verne Troyer at the film's premiere – one of the last of the French Riviera cine fest. Guests at the launch included Peaches Geldof, elegant in a deep blue satin strapless gown teamed with a feathered clutch and plaited up'do.

Cannes drew to a close on Sunday with the announcement Austrian director Michael Haneke's black and white film took the the festival's top prize, the Palme d'Or. The two-and-a-half hour movie recounts the strange goings-on in northern German village shortly before WWI.

Meanwhile winning best actress was 21 Grams star Charlotte Gainsbourg for her role opposite William Dafoe in Antichrist.
