Which actor plays GE CEO Don Geiss on 30 Rock?

Rip Torn plays GE CEO Don Geiss on 30 Rock.

Don Geiss is the head of General Electric in the show's fictional corporate universe and Jack Donaghy's boss and mentor. Jack idolizes him, treating Geiss as the model of executive authority and hoping eventually to succeed him. The character's off-screen influence helps explain many of Jack's ambitions and anxieties.

Torn appeared as Geiss across the show's early seasons, including “The C Word,” “Succession,” “Sandwich Day,” and “Reunion.” In the story, Geiss falls into a coma and later returns, while the show turns his eventual death and cryogenic preservation into an absurd corporate plot.

Rip Torn was a distinguished American actor whose other notable television role was producer Artie on The Larry Sanders Show. A common mix-up is choosing Alan Alda, who played Milton Greene, Jack's biological father, rather than Don Geiss.
