Movies being locked on Hulu is a common occurrence due to the agreements that the streaming service has with licensing studios. This means that some movies can be released exclusively on Hulu for a certain amount of time or even remain exclusive to Hulu indefinitely. In order for movie studios to get their titles and attract subscribers, they have to enter into exclusive licensing deals with streaming services such as Hulu. Depending on these contracts, certain titles may become available or be taken away at any given time, which makes them subject to locking on Hulu.
Another reason why some movies might be temporarily locked on Hulu is because of regional restrictions; for example if you live in the United States then you won’t be able access content from foreign countries (and vice versa). The regional availability of a title also changes in different parts of the world so there may also come times when you’re unable to watch something because it’s locked within your country’s borders until later down the line.
It’s important to note that different license holders often make decisions independently about where their titles appear and how long they stay put; thus it goes without saying that locking is an everyday part of our lives in media now-a-days!
