I applied UCLA, CalArts, Chapman and LMU for the 2016 fall and as a result I got rejected from UCLA and Chapman, waitlisted from CalArts and admitted from LMU. Honestly I don't remember much details about the apply process, but these school it is not hard to apply, they don't require too much documents or work sample and have clear instruction.
I believed LMU's requirements(portfolio, PS, etc.) are quite focus on "get to know you personally". They require a 5-page personal statement and a self-interview-telling-true-story and books and movies you like. I think it may because they have a small program. My GPA is quite low 80/100 and it may fall down under 3.0 under different calculation way so technically I need GRE score. But GRE actually submitted my score after they gave me the admission email, it can tell something I think. The school officer were very helpful, questions were replied efficiently with patient.
Anyway, application to LMU is quite "friendly" I think.
PS, Forgive my messy words, English is not my first language and now it is not my soberest moment. Good luck to everyone want to apply to film school!
