And here are several articles about the film:
From the Cinema Blend article on the film (from 2012):
"Mother's Day is described as a drama, and seems to bear no relation to other recent "Day" movies (Valentine's Day, New Years Day), with Duddridge's past credits appearing to be focused mainly on television. But it looks like the movie is already having some success bringing in notable names. Sarandon's recent work has her playing Joy in Showtime's underrated drama series The Big C, and she has a number of movies in the works, including the feature adaptation of Cloud Atlas. Meanwhile, Ricci's recent roles include Pan Am and Bel Ami, and she's also set to lend her voice to the Smurfs sequel. It'll be interesting to see who else joins Mother's Day."
