Channing Tatum's dramatic weight loss for his role in the upcoming film "Roofman" left people "concerned."
Tatum dropped nearly 70 pounds for "Roofman" after gaining weight for his previous role in "Josephine." The actor's latest film focuses on the story of Jeffrey Manchester, a real-life criminal who escaped prison and hid inside a Toys R Us store for months.
"Jeff is a really thin guy," Tatum explained during an interview with Variety. "He's not as big-bonded as me. I think he's tall, but he's just really wiry.
"I had just done a role earlier that year, and I got up to 240 [pounds]," he added, referring to his role as Damien in "Josephine." "I only planned to get down to 185. Once I was already going [with] the days of shooting, it kept coming off. I got down to 172."

Tatum's intense weight loss led assistant director Mariela Comitini to become "concerned," according to "Roofman" director Derek Cianfrance.
"She's like, 'That's it.' She's like, 'Get him a steak right now,'" Tatum recalled. "I was like, 'I think you're right.' This is weird."
Tatum said his transformation had "sort of an emptiness and a sadness to it."
"I would see myself and just seem hollow," he added. "The movie to me was a lot of loneliness. A real meditation for that wanting to be full. … That empty feeling sucks after a while."
