At the end of a Monday cast dinner for his movie "Henry Poole is Here", actor Luke Wilson nursed a beer, talked with friends and looked calm and relaxed.

Not so earlier in the evening when the actor and Riverhorse restaurant owner Jerry Giloman exchanged heated words.

Gillman wanted Wilson to sit down so the already-delayed dinner — prepared by Food Network chef Giada De Laurentiis — could begin.

Wilson was still talking to industry folks and wasn't ready to be seated. Gillman kept pushing. Ultimately a short argument ensued.

Will Wilson follow through on his threat to tell his A-list friends to boycott the popular restaurant at 540 Main? Stay tuned.
