A 16-year-old Auto-Trail Cheyenne 632 plays a lead role in a new film due to be released on 5 March. Supernova, stars Stanley Tucci and Colin Firth, and is directed by Harry Macqueen

Sam (Colin Firth) and Tusker (Stanley Tucci), who have been partners for 20 years, are touring the Lake District visiting friends, family and places from their time together. Tusker, who is a writer, has been diagnosed with young-onset dementia and this time spent touring is important. As the tour progresses their relationship is tested as they discover their plans for the future are not the same.

Much of the film is set within the close quarters of the motorhome, which seems to intensify the way the two men individually deal with their pain and grief – Colin Firth’s Sam is angry and anxious, while Stanley Tucci’s Tusker is quiet and resolved. It feels almost claustrophobic. This is relieved by the wonderful shots of the motorhome passing through the gorgeous landscape of the Lake District, but these and the scenes with family and friends still retain a deep intimacy and empathy. It’s beautifully filmed, with powerful and moving portrayals by the actors. Do try and see it.
