"When I fly I always ask her... You put the ear buds in and I'm talking to my mum in the lounge or whatever, and I'll be saying stuff like that, like, 'Mum, what do you think about the flight? Are we gonna be OK?' And some cat sitting next to me will get a little suspicious... I try to whisper." Billy Bob Thornton on his penchant for calling his clairvoyant mother before plane flights.
