Dr. Mierzwiak's (Tom Wilkinson) firm Lacuna is in the business of
deleting painful, inconvenient and otherwise unwanted memories - for a
price of course. The movie follows the results of this procedure on two
of his clients, the outgoing Clementine (Kate Winslet), and her shy
introverted ex-boyfriend Joel (Jim Carrey).

After their relationship runs aground, the impulsive Clementine decides
to expunge herself of her memories of Joel. Upon learning of this
(Though Lacuna - all part of the service!), Joel, partly from grief and
partly out of revenge, follows suit. During the course of the procedure,
of which the subject is conscious of their memories slipping away, Joel
begins to regret his decision. In a parallel storyline, Dr. Mierzwiak
and his Lacuna employees engage in a drama of their own.

This was a wonderful maze of a movie that traverses a multitude of
timelines, which makes the movie a little confusing at times, but
everything does eventually fall into place in the end, and the
chronology becomes clear. A second watching would provide a totally
different viewpoint of the events.

Jim Carrey does a nice job portraying a down-to-earth, somewhat
average guy - quite a departure from his usual antics. I think the
highlight performance of the picture was provided by the multi-talented
Kate Winslet, who not only does a credible American accent, but also
gives us a wholly original and fascinating character in Clementine.
