Can I sell other rights to my book?

Some people are lucky and can sell their manuscript to film, on a film option, and some people can get attention in America or Canada or Europe. But not many, to be honest. The top books can, and the books that have a very strong hook or plot can. But other times, you have to wait until the book is published and it gets its reviews, it's promoted in book shops. There's a sense of it happening, and then, as a second chance an agent has to sell the author's book. But it's a long process.
