Alyson Hannigan says it was "really fun" reprising her role as Michelle in upcoming film, American Reunion.

The 37-year-old actress joined her cast mates for the premiere at Grauman's Chinese Theatre in Los Angeles last night where she spoke about making the film.

She said that her co-stars have a renewed appreciation for the movie because of the impact that it made in popular culture.

"It was really fun," Alyson said of the filming process. "This whole experience has felt like the first film, but with hindsight, which is such a special gift."

"This is something really special and this time we get to appreciate it because we know what it means to so many people it's really cool."

Alyson is expecting her second child with husband Alexis Denisof. The couple are already parents to Satyana Marie who turns three this Saturday.
