The Big Wedding (2013)

There is a lot of acting talent in this somewhat tangled romantic comedy.  Ellie (Diane Keaton) and Don (Robert DeNiro) were once married but no more.  They have three adult children, one of whom was adopted near the end of their marriage from a woman in Columbia who gave him up for adoption in the hopes of a better life.  Don now lives with Bebe (Susan Sarandon) and weirdly they live in the house that Don and Ellie built.
On the occasion of Alejandro's wedding, there is a lot of hoopla.  If you are a fan of romantic comedy then you will be completely forgiving of the entanglements that ensue, but if not, then you are going to be annoyed.  He is marrying a childhood sweetheart who has bigoted parents with serious white collar crime issues.  His biological mother is coming and she is prim and proper whereas he is not, and she doesn't know that.  There are some very extraneous things that occur, but all in all it is a light and easy to watch movie.
