John C. Reilly has boarded Fox Searchlight's ensemble road-trip comedy Cedar Rapids, joining Ed Helms in the Miguel Arteta-directed feature.

According to The Hollywood Reporter, the story from Phil Johnston centers on a wholesome and naive small-town Wisconsin man (Helms) who, when his role model dies, must represent his company at a regional insurance conference in Cedar Rapids, Iowa, where his mind is blown by the big-town experience.

Reilly's character also is attending the conference and is a family man who sees the event as a vacation and time to let loose.

No production date has been set.
