This movie was a French production, so it's possible you're having trouble finding cast information in English.
Unfortunately, I do not have access to specific cast information for that particular movie. I can only access and process information that is publicly available on the internet.
To find the cast list, I suggest you try:
* Searching online movie databases: Websites like IMDb (Internet Movie Database) or AllMovie often list actors and actresses for foreign films.
* Searching French language movie databases: Websites like AlloCiné (in French) might have more detailed information.
* Looking for fan websites or forums: Dedicated fans of the "The Adventures of Tank" series might have compiled cast lists or other information.
I hope this helps!
