(Cover) - EN Showbiz - Colin Firth was so scared of delivering his The Kings Speech lines he locked himself in the toilet, joked Helena Bonham Carter.

The actress stars alongside Colin in the new movie, which tells the story of how Britains King George VI struggled to overcome a stammer.

Helena thinks speaking to masses of people is a nervous prospect for anyone and joked that at one point Colin hid in the toilet to escape his fear.

Most actors get into a similar, terrified, state as anybody else. Maybe because we do it more often and we are paid to get through it and we have certain mechanisms to get through it. I mean he [Colin] locked himself in a toilet recently, Helena said.

For years, Colin added. Hes only recently come out, Helena quipped.

Helena supported Colin throughout shooting the film as she knew the role was difficult.

However, she joked the 50-year-old actor didnt appreciate her hard work enough.

He doesnt recognise it but Ive been so supportive of him right from the start. Its been very tiring, she laughed on the BBC Breakfast Show. (C) Cover Media
