Continuity mistake: During the bridge collapse scene, when Olivia is crawling on the beam, she is first seen on the part of the beam that is closer to Sam. Almost instantly afterwards, she is on the part of the them that is closer to Molly. The space between the two beams increases significantly between the two shots as well.
Continuity mistake: In the premonition right near the end, you see the truck hanging over the bridge and that is how the poles and that sheet of metal kill two of the main characters. Yet when they run to the end of the bridge, the truck is not hanging over the edge.
Continuity mistake: When the bus is falling into the river, some items fall down on to the window with Issac. However the camera cuts and the items have disappeared. (00:13:40)
Continuity mistake: When Peter and Molly are talking at the start, the amount of bend in Candice's straw changes between angles. (00:05:10)
Continuity mistake: When Molly parks her car right at the start of the film, she parks and then the camera cuts to the two guys talking who walks over to Molly. When he walks over she parks her car again. (00:04:00)
Continuity mistake: During the re-creation of flight 180, the captain announces the lights are being dimmed for takeoff, and the cabin gets dark. In Alex's premonition of the takeoff in the original film, the cabin lights remained on until the explosion. Granted, Alex's actions may have changed some events (such as the teacher celebrating), but if dimming the lights was a takeoff procedure, that shouldn't have changed (either that, or Alex's vision was wrong, which undercuts the premise of the entire franchise).
Continuity mistake: Tony Todd's hairline in this film is almost completely receded compared to the full head of hair he sported in the first film, despite the events of this film being chronologically earlier.
Answer: Bludsworth's backstory has never been addressed in the series. He seems to have an intimate understanding of the supernatural nature of death but how he knows this is never explained. Why he gives the characters advice is also never explained, however he seems to be legitimately interested in whether or not the characters will succeed in cheating death because it seems to be impossible.
