'Up All Night': Christina Applegate's dad is Richard Schiff

Time to meet the extended family on NBC’s Up All Night!

EW has learned exclusively that we’re about to meet the father of Reagan (Christina Applegate), a psychologist who’s expected to be distant, quiet, and always analyzing — just what Chris (Will Arnett) needs!

And the man of the hour will be…

Richard Schiff!

The actor best known for his Emmy-winning run on The West Wing will play a contemplative dad who may come in and out of Reagan and Chris’ hectic life.

Schiff’s other recent TV credits include stints on Criminal Minds: Suspect Behavior, White Collar, and The Cape.
