* Self-reflection: Actors often watch their performances to analyze their work and identify areas for improvement. This can help them grow and develop as performers.
* Enjoyment: Depp might simply enjoy watching his own work, especially in movies he's proud of.
* Research: He might watch his older films to get a better understanding of his own acting style and how it has evolved over time. This can be helpful for future roles.
* Promotion: Sometimes actors watch their own movies as part of promotional tours or interviews, to discuss their work with fans and critics.
It's important to note that this is speculation, and there is no way to know for sure why Johnny Depp might watch his own movies.
