If you don't have a relationship with a studio exec, or an agent/attorney, another way is to get it into a highly accredited film festival, one where studio execs would attend, or at least have a representative from their office attending.
If it's not getting accepted into film festivals, get some feedback from qualified mentors. Once you get enough positive feedback, create a buzz campaign around it and then host your own screening.
These are just a few of the ways. Good luck!
