O’Connor and Straughan adapted their screenplay from John le Carre’s thriller of the same name. O’Connor also adapted The Men Who Stare at Goats from the book by Jon Ronson. That 2009 movie starred George Clooney, Jeff Bridges, Ewan McGregor, and some goats.
Many of le Carre’s books have been adapted into film. Most recently 2005′s The Constant Gardner, for which Rachel Weisz won an Oscar. Tinker Tailor… was even a 1979 mini-series produced by the BBC.
If you’re local, the Wilton Town Hall Theater is scheduled to start playing Tinker Tailor Soldier Spy on Friday, January 27. If you’re not local, it’s worth the trip!
