The duo will star in the Lionsgate film, directed by Jonathan Levine, according to The Hollywood Reporter.
Skarsgard will play a prime minister of Canada who is described as "very handsome," while Park will portray Flarsky's (Rogen) boss at the newspaper.
In the film, Rogen plays Fred Flarsky, an unemployed journalist who is a victim of misfortune and his self- destructive ways.
