Benedict Cumberbatch in Parade's End

“And Cumberbatch found his acting skills further stretched by the demands of this ancient sport. One scene, which involved a group walking and talking, culminating in Cumberbatch tee-ing off, had to be repeatedly reshot as words and bodies and timing got muddled. Finally, everything fell into place and Cumberbatch swung his club magnificently - unfortunately forgetting to hang on to it.” - The Spectator
