Pierce Brosnan: My, Oh Mia!

Pierce Brosnan gets the support from his wife Keely Shaye Smith at the premiere of his new movie musical, Mamma Mia! at the Ziegfeld Theatre Wednesday in New York City.

The 55-year-old actor and costar Meryl Streep arrived in a BMW Hydrogen 7s – the world’s first hydrogen cars for everyday use. Both stars happily mugged for cameras and fans with their eco-friendly ride of choice, and one of Hollywood’s “must haves” for green-minded stars.

Mamma Mia! opens in theaters nationwide this Friday, July 18.
