The Love Patient (2011) on Netflix

Paul is a success who has gone stale with his work and his life. He has lost the love of his life but they are still co-workers. So he decides to "get" cancer so he can be popular again with Brad. When the (supposedly fake) test result comes back, he is diagnosed with an actual spot on his lungs which has "metastasized" and he is put to bed rest and on a drug regimen. But is the diagnosis real or faked or an "intervention" by his friends, co-workers and ex-lover... His family and friends do, in fact, assemble around him and hilarity ensues - with some familial bickering.
