Blake Lively, one of the three main stars of the movie The Shallows (the other two being a CGI shark and a seagull named Steven Seagull), was interviewed by Australia's Sunrise show, where she talked about how physically challenging filming the movie was. She also mentioned that she started shooting the film just eight months after having a baby (her first child with husband Ryan Reynolds, a daughter named James), which required her to get super physically fit quickly after giving birth. But she explains that she's not a fan of how "celebrated" it is for moms to get back their pre-baby bodies in a rush.
