The Night Manager (Seasons 1-2) and Thank God You're Here (Australia)

Shows where people are pretending to be someone else.

The Night Manager

When a humble hotel manager aka "the Night Manager" (played by Tom Hiddleston) becomes privy to a terrorist level threat (whose mastermind is wonderfully played by Hugh Laurie) he gets involved in some secret agent spy hi-jinx to take them down. This currently two season British show is really good, and I quite like that our protagonist has to often rely on his charm and wit instead of brute force violence. However it's also a great example of "gee, you wouldn't be in this mess if you just killed your enemy earlier huh?". Despite that annoyance, I still recommend it. 

Thank God You're Here (Australia)

This comedy show has a few iterations depending on country, but for the Australian version there are six seasons of sending four (or five) comedians through a door on a stage where they must act out a scene without knowing anything about it before hand - forcing them to make stuff up on the spot. They might have some hints with the costume of props they are provided with, but especially as it is in front of a live audience the results are always very entertaining! Now as you might expect, some people are not as good as others but there are a number of fantastic and hilarious ones making the whole thing worth watching. If you can find it, I recommend giving it a try.
