Funny, I was making something similar myself!

Even using the same API... what a small world. I'm glad I can use yours instead now! I was actually thinking it would be fun to use Python to search the Tv Maze API for cast of different shows you like and then find common shows with the same actors. Might be a waste of time though. Nice job on Tello.
