Polly considers herself a serious actress, waiting for the role that best suits her considerable talents. But her acting dreams start to crumble when her identical twin Amy lands a lead role in an HBO show and starts dating co-star Jared Leto. A disastrous trip to LA does little to help matters, but the unbearable situation becomes a little better when Polly discovers that she can use her sister's celebrity to her advantage to get free clothes, free booze and casual sex. The consequences are very funny – and awkward. A very promising feature debut by Gregory Erdstein, That's Not Me is a clever, knowing comedy with a winning dual performance by Alice Foulcher.
