TV WORTH WATCHING:

KILLING BIN LADEN

ARGO: INSIDE STORY

DISCOVERY, 9 p.m. & 10 p.m. ET; 2/23/2013

As a pre-Oscars treat, Discovery Channel has shuffled its lineup tonight to repeat two documentaries tied to this year’s Best Picture nominees. The first gives a nonfiction retracing of the same steps presented in Zero Dark Thirty, about the search for Osama Bin Laden.

Part two of Discovery Channel’s special pre-Oscars doubleheader is a one-hour special in which the CIA’s Tony Mendez, among others, recounts the real-life events leading to the daring escape of six Americans during the 1978 Iran hostage crisis. This version is a repeat of the little-remembered, now-topical special, but with new narration, provided by Argo co-star Bryan Cranston.
