Cattrall, appearing in a West End production of "Whose Life is it Anyway?," sold tickets, programs and ice cream as well as the Evening Standard in the Visit London campaign. She also is donating her fee to benefit tsunami victims.
"There's so much happening artistically," Cattrall said. "I feel very connected to London. My first taste of theatre here was when I was 10 years old."
Former "Dawson's Creek" star Joshua Jackson, who took a turn behind the wheel as a cabbie, also is part of the go-to-London campaign. Jackson is starring in "A Life in the Theatre."
