The cast of American Pie are back on board for a sequel and took a trip around London on a double-decker bus to celebrate their comeback.

Stars including Tara Reid, Jason Biggs, Mena Suvari and Chris Klein were in the capital to promote the follow-up to the hit 1999 teen comedy.

The new film sees some of the original cast, older but not necessarily wiser, return to their home town for a school reunion.

Suvari said filming American Pie: Reunion brought back happy memories of the first film in which she played Heather.

She said: “I remember when it came out.

“In the summer of ‘99 I was working in Minneapolis on Sugar & Spice, and I was sad that I missed the premiere. We were playing cheerleaders in the new film and shooting a football scene, so there were a couple thousand extras. All of a sudden, I started to hear people shouting ‘Choir Chick Heather’.

“It freaked me out, and then people wanted my autograph, which completely took me aback.”

Co-star Tara Reid said she enjoyed playing her character, Vicky, again.

She said: “It’s fun because I know Vicky so well.

“It’s like having your first pair of jeans and putting them right back on again.”

The film is released in the UK on May 2.
