My knowledge is based on the data I was trained on, which doesn't include detailed information about the cast of every film ever made.
To find that information, I recommend checking these resources:
* IMDb: IMDb (Internet Movie Database) is a great resource for movie information, including cast lists. Search for "Pe litoral mi-a ramas inima - 1961" on IMDb.
* Wikipedia: If the film is notable, there might be a Wikipedia page about it that includes information about the cast.
* Film databases: Some online databases are dedicated to film information and might include "Pe litoral mi-a ramas inima - 1961" with its cast list.
* Movie review websites: Websites like Rotten Tomatoes might have information about the film and its cast.
Good luck finding the information you need!
