Tom Cruise
The Mission: Impossible star was pushed to his absolute limit - and not by his death defying stunts - during a infamous television profile interview with Australian journalist Peter Overton on 60 Minutes on 13 February 2005. Overton repeatedly crossed professional boundaries by intensely probing Cruise for intimate details regarding his divorce from Nicole Kidman, specifically asking about their co-parenting dynamic. Cruise refused to take the bait, firmly telling the reporter, "You're stepping over a line now", before demanding Overton "put his manners back in", cutting the segment entirely short and calling an immediate end to the filming.
