Has Rodrigo Santoro left any series recently?

I'm not sure if he left a series "recently" - that depends on how far back you consider recent. Rodrigo Santoro is always working on international projects, but keeping up with his career in real time is tricky because he works a lot between Brazil and the United States, and information doesn't always circulate fast here. If you saw something specific in the media that you're thinking of, it'd help to clarify which series you're asking about, because then I can give you a more accurate answer.

Which series are you following? Rodrigo Santoro is the type who disappears from the radar for a while and comes back with something big, so it's hard to keep up without following his social media. The tip nobody gives you is to mess around on IMDb and filter by "recent" - that way you see his complete timeline and can tell right away if he's in production or just wrapped something recently, without having to depend on whatever news is floating around out there.
