Mother's Day: It's an actual movie! It will be out in 2016, who knows what release date. Deadline has announced that its cast just keeps growing: Julia Roberts, Jennifer Aniston, Kate Hudson, are being joined by Timothy Olyphant, Shay Mitchell, Britt Robertson, Jack Whitehall, Aasif Mandvi, and Loni Love.
It's just as SNL parodied (New Years Eve, the sequel) and 30 Rock spoofed (MLK Day): Pile up professional actors, add a holiday, stir, release.
