According to Variety, Mandy Moore has signed on to star as Diane Keaton's daughter in Gold Circle Films' Because I Said So for helmer Michael Lehmann. Universal Pictures has also closed a deal with Gold Circle to distribute domestically.

Penned by Karen Leigh Hopkins and Jessie Nelson, the pic will star Keaton as a meddling mother who, in order to prevent her youngest daughter (Moore) from following in her footsteps, attempts to set her up with the right man.

Shooting begins late this month.
