While some actors rely on prosthetics for movie transformations, some actually gain or lose weight to embody their characters. Renée Zellweger famously gained 30 pounds to play the titular role in 2001's Bridget Jones's Diary, repeating the process again for the 2004 sequel, Bridget Jones: The Edge of Reason. By the time she filmed Bridget Jones's Baby, however, the Oscar winner was tired of talking about her weight. "I put on a few pounds. I also put on some breasts and a baby bump," she told British Vogue in August 2016.
