So I Married an Axe Murderer is a 1993 dark romantic comedy starring Mike Myers and Nancy Travis. The film follows Charlie MacKenzie, a San Francisco beat poet with a fear of commitment. He meets Harriet, a charming butcher, and falls for her—until he starts suspecting she might be the infamous "Mrs. X," a woman who marries men and then murders them on their honeymoon.

As Charlie digs deeper into Harriet's past, he uncovers eerie coincidences that match the tabloid stories about Mrs. X. His paranoia grows, leading to a series of comedic misunderstandings and frantic investigations. But is Harriet really a killer, or is Charlie just sabotaging his own happiness?

The film blends quirky humor, mystery, and romance, and while it wasn’t a box-office hit, it has since gained a cult following for its offbeat charm and memorable performances.
