London: 'King's Speech' star Colin Firth says receiving the best actor Oscar was a numbing experience and he does not have any memory of the proud moment.

The 51-year-old star does not remember accepting the Golden Globe and Oscar for his portrayal of George VI in the British drama, a news daily reported.

"It has a slightly numbing effect...that's what's completely extraordinary but I think when major things happen to us, whether good or bad, there's a slight shock," the actor said.

While accepting the Golden trophy this year, the actor had joked, "I've a feeling my career's just peaked."

Firth, however, feels that the win has given him more freedom in his career.

"In terms of one's attitude to it, you can either see it as pressure to live up to something or as taking the pressure off and going, 'Well, I've got that now. I'll do whatever the hell I please'. And that's a far more pleasant way to see it," he said.
