Used Canon T2i with kit zoom lens is a great place to start.
After you've made a few tests, you can scrape together $90 for a used Canon EOS 50mm f1.8 and start really playing with cinema looks...
Build up some lighting kit over the next couple months.. clamp lights, work lights, etc.
After a few months you will have a good prime lens, a zoom, a camera and a few lights.. next you need to upgrade your tripod!
After that you may want to spend some time deep diving into you computer needs. Really learning your editing software etc...
Once you have HIT the limits of your gear you may want to consider "hacking" your camera with Magic Lantern... which moves you to the next level camera geekdom..
Then you can start cruising pawnshops\ebay for M42 lenses (m42 is a screw lens mount that is readily and cheaply adaptable to the T2i, lots of selection.) To correct an earlier post, you CAN adapt almost ANY lens to the T2i easily, just not old Canon FD ones, and a few other mounts.
