Salem's Lot (1979) 
3hrs just fly by when you watch Salem's Lot, there are so many amazing scenes, including Danny Glick tapping on Mark's window, Mr Barlow materialising from a pile of rags in the Petrie kitchen and Mr Barlow awaking inside his coffin. However the one scene that freaked me out the most as a kid is when Ned and Mike are collecting the 'sideboard' from the docks to bring it back to the Marsden house. It still amazes me to this day that it's a TV movie!
