This looks like fun...
Ordinarily, I'm not a big fan of crossovers, but this amuses me.

From Digital Spy:

Filming of two new episodes of cult TV series Red Dwarf began filming over the weekend on the set of Coronation Street.

The two-part special, entitled Red Dwarf: Return To Earth, will see Dave Lister - played by Craig Charles - finally succeed in his desire to make a comeback to his home planet.

As part of the plot, Lister's crew, made up of Rimmer (Chris Barrie), Kryten (Robert Llewellyn) and Cat (Danny John-Jules), go in search of him and instead bump into Charles's Corrie character Lloyd Mullaney in The Rovers Return.

As part of the filming, Weatherfield's Steve McDonald (Simon Gregson) also made an appearance.

In an exclusive interview with DS at the end of last year, Charles teased: "I can't really give the storyline away but it's a fantastic one. It's really quite weird and sees me playing quite a few characters, some of them I've already played on television. That's all I can say."

Laura was a regular Corrie watcher when we met and got me hooked on the show. I can't stand American soap operas, but this is so different from American soaps there should be a different name for the genre. Coronation Street is about a mainly working class neighbourhood in Weatherfield (apparently a fictionalized version of Salford, part of Greater Manchester). There's a pub, a small cafe/greasy spoon, a small underwear factory, a garage, a few small shops, and the homes of the people who work there. The show started in 1960 as a northern TV version of the then-popular UK kitchen sink drama; the one character who's been with the show from the beginning was the one kid from the street who was going to university and dealing with class and culture conflicts. The show hasn't exactly retained that gritty realism, but it's a long way from being glossy and glamourous.

Craig Charles joined the show a few years ago. He plays a single, middle-aged guy from Liverpool who's had troubles with women and finds himself buying into a small taxi business. He's had more a supporting role than a major one, but he's been there long enough now that when I see him, I see Lloyd from Streetcars, not Lister from the Dwarf. They aren't the same character, of course, but the novelty of seeing someone on Corrie I was familiar with from another series took some time to wear off.
