As of October 2023, "Avatar" (2009) holds the title for the highest-grossing film of all time, surpassing "Titanic" (1997) and briefly losing to "Avengers: Endgame" (2019) before reclaiming the top spot after a re-release in 2021. However, if you are asking about the most watched movie in terms of viewership, that can vary based on different metrics and platforms. Box office gross does not necessarily correlate with total viewership, especially with the rise of streaming services.

"Stuff and Dough" (original title: "Banițele") is a Romanian film that combines elements of drama and dark comedy, focusing on two young men who get involved in a risky scheme involving a pizza delivery. The film explores themes of friendship, desperation, and the struggles of youth in a post-communist society. While it may not have widespread recognition, it has been praised for its storytelling and character development. If you enjoy international cinema with a mix of humor and social commentary, it’s worth watching.
