Ewan McGregor was shamed into rallying his co-stars' spirits on a movie set after receiving a frightening text message from his fighter pilot brother.
The Trainspotting star and his fellow cast members were loudly complaining about the quality of coffee in their make-up trailer when his brother Colin sent a harsh reminder of life outside Hollywood.
Colin was serving with Britain's Royal Air Force in Iraq at the time, and his account of a night under heavy enemy bombing had a profound effect on the actor.
MCGregor tells Live magazine, "I can't touch what he did for a living. I remember making a film and being in the make-up bus with a load of actors, and we were all moaning about the coffee. Then my phone beeped and it was a message from my brother: 'Emergency landed into Basra last night. Slept under canvas next to the runway. We were mortared all night long. Hope you're well. Colin.'
"I looked up and said, 'We've got to stop moaning about the coffee, people. Really, we've got to stop.'"
