A film that focuses on behind the scenes in a classic movie production studio, where the movie director was inspired to shoot a retake for an alternative ending despite multiple challenges and restrictions ahead of it, while a new genre of cult classic was born in the making. The flow of the storyline is actually extremely complicated to execute, yet the script was able to handle the movie within movie seamlessly. A great proof of concept that works well though it may not be a crowd pleaser, luckily it's still pretty entertaining amid the chaos. The final act of that one take sequence is definitely the reason why this movie was selected for Cannes screening of this year, it's simply brilliant.
