There is a foreign comedy film, but I really can’t remember the name. There is a woman in the film who is extremely fat. At the beginning of the film, this woman marries the male protagonist.

Norbit

Norbit was often bullied by his friends. Only the beautiful Kate was his best friend. The two even held a childish and cute wedding ceremony when they were children. Of course, not all good stories have happy endings. Norbit's marriage was a tragedy. His wife is not Kate, but the huge, ton-sized super fat woman Rasputia (played by Eddie Murphy). Rasputia is rude and has a bad temper. Norbit is submissive and miserable under her "leadership". One day, the god of fate suddenly came. Kate (Thandie Newton), who has been away for many years, returns to the town again, giving Norbit new hope.
