1. Watch something else: The easiest way to remove a movie from your "Recently Watched" list is to watch something else. Netflix prioritizes the most recently watched content, so new viewing activity will push older movies further down the list.
2. Use the "Remove from Continue Watching" option: If you're using the Netflix website or app, you might find a "Remove from Continue Watching" option next to the movie you want to hide. This will remove the movie from the "Continue Watching" row, but it might still appear in your "Recently Watched" list.
3. Sign out of your account: While this is a drastic measure, signing out of your Netflix account will completely clear your "Recently Watched" list. However, this will also sign you out of all devices you're logged into.
4. Clear your browsing history: On some devices, you can clear your browsing history, which will remove any trace of what you've watched, including from the "Recently Watched" list. However, this will also delete your history for other websites and apps.
Important Note: There's no official way to completely and permanently delete your "Recently Watched" history. However, the above methods can help you manage what appears on your list.
