According to the Daily Mirror, Preston’s Off the Rails co-star Sally Phillips discussed the late actor while on the British talk show Loose Women on July 22. Phillips said she and Preston got close while filming Off the Rails in Spain in 2019, but Preston kept her battle with breast cancer a secret from the cast and crew. “She was so bloomin’ beautiful. And so vibrant, and you would never have known. She was so professional,” said Phillips. Phillips also pointed out that this seems to be common in Hollywood. “That’s what people do—they go through it on their own because of worries about insurance for the film and working again afterwards,” she said. “We’ve had a couple of high profile examples of that recently, haven’t we? Chadwick [Boseman] and Helen McCrory didn’t tell anyone.” RELATED: How Old 100 Iconic Stars Would Be If They Were Alive Today.
