Excellent!
It's not quite <em>'<a href="https://letterboxd.com/film/bridge-of-spies/" rel="nofollow">Bridge of Spies</a>'</em>, but <em>'The Courier'</em> is too an awesome MI6/CIA/KGB infused flick. The two films tell tales regarding the Cold War, with the 2015 release narrowly a notch above this. Both have outstanding lead performances though.
Benedict Cumberbatch is magnificent throughout, especially towards the end - the bald look suits him incredibly well, I must say... need him in a drug kingpin sorta role looking like that! In all seriousness though, I think this is my favourite Cumberbatch performance (from what I've seen thus far) - utterly brilliant!
Merab Ninidze (also in BoS, albeit minorly) also puts in a top display, as he does in television's <em>'<a href="https://en.wikipedia.org/wiki/McMafia" rel="nofollow">McMafia</a>'</em>. Jessie Buckley also gives a performance of note, which says a lot about her acting abilities given she doesn't feature all that heavily.
Astutely paced, builds terrific tension and features some cracking acting. Fantastic film!
