First, congrats for regrouping after such a difficult experience.
I agree - you really should broaden your list of target schools. As you can see here, there are just 142 applied math transfer admits at UCB, UCLA had even fewer.
I am not suggesting you not apply - go for it but, understand its a long shot. At the same time use TAG to guarantee a path somewhere like UCI, or even a CSU like LB or CPP. all of which are proximate enough to the film industry
I’d also echo that you don’t need to speed through school. You won’t be the only 22 year old on campus. For a host of reasons, many CC transfers spend 3-4 years or more before moving up to a CSU or UC. Smell the roses a bit, take unrelated/non-required classes - you might just spark a life long interest.
Good luck.
