Good question! I know several people who got their shows green lit by various studios. Alex Hirsch was my calarts classmate and got his show Gravity Falls green lit at Disney several years ago. His student films were very strong at Calarts so he was being heavily recruited right out of college and it inevitably led to Gravity Falls. I think there are a lot of challenges dealing with the executives who make the decision on whether to make your show or not. Essentially, in that scenerio you have to put your sales hat on. You really need to sell your ideas if you're going to succeed in pitching. No better way to do that than to practice as much as possible. Talk in front of audiences and develop a knack for pitching your ideas. Telling your story in a compellling and concise way. JG Quintel is another friend who got Regular Show through at Cartoon Network. The guy went for it! And Penn Ward, who was a like three years ahead of me at Calarts made his dream come true with Adventure Time. You wouldn't think from meeting him that he was great at pitching because he's rather quiet and low key. But obviously he has amazing skills in selling ideas to executives. His student films at calarts were also very popular and stood out so that always helps. I think that there are opportunities to pitch at most of the studios. It's a political process but once you get your foot in the door, you'll have the chance to grab it. i think most people just don't go for it! Make the decision early on that this is what you want so you will not hesitate when the opportunity comes up!
