Not too sure, the tv guide says:
If you're worried about gaining the odd pound over the next few days, this should put things in perspective. It's a great, wobbling tale of about a Rochdale man who's so obese he becomes a tourist attraction. Timothy Spall plays warm-hearted giant Georgie Godwin; his agent Maurice (Bobby Ball at his most terrifying) charges foreign tourists to line up in Georgie's front room and hear him sing bad karaoke. The script is co-written by Caroline Aherne and has her characteristic mix of broad comedy larded with touching moments. The opening scenes rely too heavily on caricatures, but stick around and things warm up. Music by Badly Drawn Boy lends the whole thing a poignancy the script doesn't always manage, but by the end you're left with the lingering feeling that you've seen a modern fable.
