I would also include anything that was initially a flop on its original release but then found a following later such as movies like Momento. This still counts as commercial failure for the sake of this question.

The appearance of Fight Club on your list surprised me - I thought it did well. But I looked it up - it was #1 on opening weekend but ultimately only turned a profit of $10m, which is indeed a flop. Wild considering how well regarded it is now.
