Ex-Neighbours star Jason Donovan is to appear with former EastEnders actress Martine McCutcheon in ITV1's upcoming soap opera about surfing in Cornwall.
Donovan is currently relaunching his pop career
The former soap stars play ex-lovers in Echo Beach, a post-watershed drama set in fictional coastal resort Polnarren.
The show will run in tandem with Moving Wallpaper, a sitcom starring Ben Miller as a hapless producer desperate to make Echo Beach a success.
The two shows are being made by Kudos, producers of BBC One's Life on Mars.
Donovan and McCutcheon will make cameo appearances on Moving Wallpaper, set to begin transmission alongside Echo Beach early next year.
According to an ITV1 spokesman, jokes, characters and subplots will cross from one show to the other over the course of 12 weeks.
Both series are the brainchild of Tony Jordan, a lead writer on EastEnders and co-creator of Life on Mars.
