Former Lost villain Michael Emerson (pictured) is to guest star on an episode of NBC drama series Parenthood later this year.

According to EW, Emerson will play a character called Amazing Andy who is hired as a children's entertainer at Max's birthday party.

Andy, like the show's main character Max, will be portrayed as suffering from Asperger's Syndrome.

Emerson is best known for his role as main villain Ben Linus on ABC's recently concluded series Lost.

Emerson's appearance on Parenthood is scheduled to air in March.
