Tinker Tailor Soldier Spy - The original British version with Alec Guinness but I think it's technically more of a mini-series, still I've heard people claim they've seen it in theaters back in the 70s. A really good film, if very British, which means most of the action is just understanding the context of events cause there is very little action to speak of and it's mostly listening to guys talking in hotel rooms, fields, and inside cars using elaborate codenames that often don't make much sense. The flashbacks are very jarring cause they are very long and sometimes happen without telling you, but otherwise it's a really good spy film though you seriously need to pay attention cause the film seriously just spills out all this information at the beginning which is important but doesn't seem like it is at the time. Alec Guinness does a superb job in his role and the cast was really well thought out and entertaining.
