Originally titled The Baster, for reasons that will become obvious, The Switch is a forthcoming comedy starring Jason Bateman, Jennifer Aniston and Jeff Goldblum.

The trailer appears to pretty much give away the whole film but this looks like a pretty by-the-numbers romantic comedy so if you know the premise you can probably take a good guess at where the plot goes anyway. I can’t see much in the trailer that suggests that this is going to be anything particularly interesting or funny. What do you think?

The official synopsis is as follows

JENNIFER ANISTON stars alongside JASON BATEMAN in this offbeat comedy as Kassie, a smart, fun-loving single woman who, despite her neurotic best friend Wally’s (BATEMAN) objections, decides it’s time to have a baby—even if it means doing it by herself … with a little help from a charming sperm donor (PATRICK WILSON). But, unbeknownst to her, Kassie’s plans go awry because of a last-minute switch that isn’t discovered until seven years later when Wally finally gets acquainted with Kassie’s cute— though slightly neurotic—son.

The US release date is set for 20th August 2010 with no UK release date scheduled yet.
