Kiera Knightley blames profession for distancing her from good friend Sienna Miller

London, Aug 11 : Hollywood actress Kiera Knightley misses good pal Sienna Miller, as the two have lost touch post shooting of the movie 'The Edge of Love'.

Apparently, they became good pals during the making Dylan Thomas movie 'The Edge of Love' in Wales, but as soon as the shooting got over, both of them got busy with their own lives, and lost touch.

"I love Sienna, I think she's a wonderful actress, but we've been like two ships passing in the night recently," the Daily Express quoted Knightley as saying.

"I think that's what's lovely but also sad about acting, you get incredibly close to people and as soon as it's over, you don't see each other," the actress added.

The star fondly recalls her days of shooting with Miller and is not reluctant to admit that its very difficult maintaining friendship in her career.

"You're away from home, it's a very intense relationship and then it's not any more," she said.
