The Anchorman actor will reunite with his Wedding Crashers co-stars Vince Vaughn and Owen Wilson in the Shaun Levy-directed comedy, Variety reports.
Ferrell will make a cameo appearance as the brother-in-law of Wilson's character, a home electronics salesman who apparently has no qualms about what he says to his attractive customers.
Vaughn and Wilson will play old-school salesmen who decide to 'skill up' by taking internships at a large technology firm when work dries up.
Ferrell will next be seen alongside Zach Galifianakis in political comedy The Campaign, and has begun work on a sequel to Anchorman: The Legend of Ron Burgundy which will reunite the majority of the original's core cast.
