Answer: Both “Have you seen that movie?” and “Have you watched that movie?” are grammatically correct and commonly used in English.
The choice between them may depend on subtle nuances in meaning or personal preference.
“Have you seen that movie?” is a more general and commonly used phrase. It simply inquires whether the person has had the experience of watching the movie, regardless of whether it was in a theater, on television, or via streaming. “Seen” is a more general term and simply asks whether the person has had the experience of viewing the movie, regardless of the circumstances or level of engagement.
“Have you watched that movie?” is slightly more specific and may imply a deliberate act of viewing the movie, suggesting a more focused or intentional viewing experience. “Watched” may imply a more deliberate or focused act of viewing, suggesting that the person actively sat down to watch the movie.
In everyday conversation, the two phrases are often used interchangeably, and the choice between them may depend on personal preference or regional variations in language usage. Both convey the same basic question about whether the person has viewed the movie in question.
