Fangoria Magazine did a behind-the-scenes story during the making of the film while it was shooting under the title "The Reaper". The title was changed to "Venom" shortly before its release.
The town 'Backwater' that the movie is set in, seems to be deserted. No people are out and no shops or anywhere are open - and it's a pretty big town. The only place that is open is the diner.
When Sean gets out of the lake, he is wet and wearing a bathing suit. When he mounts his motorcycle less than 30 seconds later, he is fully clothed and completely dry.
When Sean is pulled through the window with the chain by Ray Sawyer, the whole window behind him shatters. However, a few moments later inside the house - the window has somehow repaired itself.
