I wanted to watch The Switch about a month ago but somehow —I blame Patrick Wilson and the short title—I ended up watching The Ledge instead, which was quite the opposite of the light romantic comedy I was expecting to see. I double-checked this time and I was finally able to watch it.
The film revolves around Wally (Jason Bateman), a neurotic man who has a hard time finding his soulmate, and his best friend Kassie (Jennifer Aniston), who decides to get artificially inseminated. Wally doesn't like the idea, mainly because he's in love with her though he hasn't realised it yet. At Kassie's insemination party, he gets drunk, he accidentally dumps the donor's (Patrick Wilson) sperm in the sink and decides to replace it with his own. He forgets completely about it, and Kassie leaves New York as she doesn't feel like it's the right place to raise a child. Seven years later, she comes back with her son Sebastian (Thomas Robinson) and Wally starts to notice striking resemblances between the boy and himself. In the meantime, Kassie becomes intimate with Roland, the sperm donor.
