Review Summary
Your implementation is well-structured and almost complete, but there's a critical bug in the create method of app/managers.py that prevents database insert operations from working. On line 21, the column name is incorrectly capitalized as Last_name instead of last_name. This mismatch with the actual database column name will cause all create operations to fail with a "no such column" error when the SQL INSERT statement is executed.
The fix is straightforward: simply change Last_name to last_name in the INSERT statement to match both the Actor dataclass attribute and the actual database schema.
This is a blocking issue because the create method won't function at all as written, but it's an easy fix that shouldn't take long. Once corrected, all core CRUD functionality should work properly. Keep going — you're very close to having a complete and working implementation!

The SQL column name has incorrect casing: Last_name should be last_name to match the Actor dataclass attribute and expected database column name.

Review Summary
I am requesting changes because there is a committed SQLite database file (cinema_db.sqlite) in the repository, which directly violates the requirement not to push DB files [CHECKLIST ITEM #1]. Functionally, your solution is solid: Actor is correctly implemented as a @dataclass, and ActorManager provides working create, all, update, and delete methods with the correct parameters and behavior. The manager correctly opens the SQLite connection in __init__, uses parameterized queries, and all() returns an empty list when there are no rows.
The blocking issue is purely about repository hygiene and checklist compliance, not your Python logic. To fix it, remove cinema_db.sqlite from version control (for example, with git rm cinema_db.sqlite), commit that removal, and rely on the existing .gitignore entry so it does not get re-added. Once that file is no longer tracked, your implementation will fully meet the task requirements. Overall, the code itself is well structured and clear, so after cleaning up the DB file, you should be in great shape.

Review Summary
Your implementation is approved. All requirements have been successfully met: the Actor dataclass is correctly defined with id, first_name, and last_name attributes; the ActorManager class implements all CRUD operations with proper method signatures; the create method now correctly uses lowercase column names (first_name, last_name) that match the dataclass attributes and database schema; and the .gitignore properly excludes database files. The critical bug from the previous review has been fixed, and there are no remaining blockers. Your code is complete and ready for use.
