What is your favorite (fairly common) font? Any font suggestions for the titles at the beginning of a film?

I’m not much of font master- I use a few basics like Courier, NTR, and Arial. I’m currently settling on the opening titles for my film and I’m experimenting with different fonts. Do you have any favorite fonts that are worth recommending? They need to be simple and look good bolded so they are very visible over the image. They need to be a fairly common font since I have to redo the titles eventually in a different program (currently in fcp). A few filmmakers I know of have kind of branded themselves by the fonts that they use and I’d like something that I might get comfortable using again should I be fortunate enough. Any thoughts are appreciated…
