TV briefs: ‘Lincoln’s Last Day,’ ‘The Americans’ and ‘Mr. Robinson’

Honestly: April 14 will mark the 150th anniversary of the assassination of President Abraham Lincoln. This critical moment in American history will be examined in “Lincoln’s Last Day,” a one-hour Smithsonian Channel documentary that retraces the events leading up to the fatal shot.

It debuts at 8 p.m. April 13 on the cable channel.

Checking in: Jeff Fahey has joined the sophomore season of Robert Rodriguez’s “From Dusk Till Dawn: The Series” in a recurring role.

Fahey has been cast in the role of Uncle Eddie Cruickshank, the man who raised The Gecko Brothers after their father died in a fire; he runs a TV/appliance repair shop in Houston, Texas — but it’s really a cover.

Spy games continue: FX has ordered a fourth season of the award-winning drama “The Americans.”

It will return for a 13-episode fourth season in 2016. Four episodes remain in the current season, which will conclude with the season finale on April 22.

“The Americans” was honored by the American Film Institute as one of the TV Programs of the Year in 2014 for its first season and again in 2015 for its second season. The series has also received three Primetime Emmy Awardnominations.

Coming soon: NBC has set Wednesday, Aug. 5, for a new hourlong block of comedies as “Mr. Robinson” will premiere at 9 p.m. immediately followed by “The Carmichael Show” at 9:30 p.m.

In addition, new summer alternative series “The Island” will immediately follow “American Ninja Warrior” on Mondays starting May 25 while “I Can Do That” will have “America’s Got Talent” as its Tuesday lead-in beginning May 26.

Returning reality series “Food Fighters” (July 2), “Hollywood Game Night” (July 7), “Running Wild with Bear Grylls” (July 13) and “Last Comic Standing” (July 22), as well as second-year comedy “Welcome to Sweden” (July 19), will all come back for new seasons on NBC.
