Coming soon to a stage near you

We weren't sure what to expect when we heard that iconic Abba musical Mamma Mia was set to hit the big screen. Thankfully, Meryl Streep's brilliant star turn won us over (with a bit of help from Pierce Brosnan and Colin Firth, of course). Instead of films based on musicals, the new trend is to base stage shows on films. The Wizard Of Oz capitalised on the success of Wicked (and the popularity of the original film) with a magical season in the West End this summer and next year, we can look forward to a London run for iconic cross-dressing tale Priscilla, Queen Of The Desert. In the meantime, Sister Act is looking for a London venue to call home and it's rumoured that 9 To 5, based on the classic Dolly Parton film and with songs written by the queen of country herself, may be coming to town, too. We can even, erm, look forward to a Spider-man musical in 2009, featuring music by U2. But as fabulous as a good musical can be, there's nothing more tragic than a lame one.
