Why didn't he just store it in his garage next to his corvette where it's definitely safe

Studios don't invest in movies like they used to. You may get a small budget film here and there that does ok at the box office and makes good profit in DVD sales but now DVD sales are non existent. If it can't make it at the box office a lot of studios don't want to invest and funnel it into these generic films running on algorithm and animation is cheaper usually.

Thing is I think a lot of people would take a low budget film that doesn't take itself serious and people could enjoy it. Theres this huge live action gap where you get these horrific films that adults die from cringe trying to watch or a 150 million dollar marvel movie. Theres also a huge lack of great comedic actors like your Jim Carey and such to make those movies. Sonic was a great movie that could be enjoyed by all but not bw terrible for adults. So you get these direct to streaming movies or a wannabe blockbuster but very few offerings in-between in a live action format.

Is that Jack of Blades?
