Closure

I'm assuming there's no sequel to this movie and Hannibal flies off into hiding. Am I correct? I was under the impression Red Dragon was a sequel to Hannibal until I watched it for the first time last week and realized it was a prequel to SOTL. I dont understand how Hannibal keeps flying across the world, considering he's on the list of America's Most Wanted. He left Florence and flew to the US. Then at the end, he left Virginia by plane and flew who knows where.
