"Mamma Mia!" Movie Premieres in London

The ABBA-inspired musical opens in film form in London with other release dates coming up worldwide. The all-star cast includes Meryl Streep, Pierce Brosnan, Amanda Seyfried, and Colin Firth frolicking through the Greek islands. Hm... do I sense a surge in travel to Greece later this summer?
