Don`t want to play `Mr Bean` any more: Rowan Atkinson

London: Actor-comedian Rowan Atkinson fears the end of his beloved comedy creation `Mr Bean` is near as playing him has become `childish and sad`.

`Mr Bean` made his most recent appearance at the opening ceremony of London Olympic games 2012, but the 57-year-old actor now wants to concentrate on more serious acting roles, reported Daily Star online.

"The stuff that has been most commercially successful for me - basically quite physical, quite childish - I increasingly feel I`m going to do a lot less of," Atkinson said.

"Apart from the fact that your physical ability starts to decline, I also think someone in their 50s being childlike becomes a little sad. You`ve got to be careful," he added.

Atkinsons` famous bumbling character Mr Bean debuted in 1990, with the show running for five years and spawning two successful movies and a cartoon spin off.
