Why It Would Rock: "There can only be one!" Highlander is about a centuries-old battle between a slew of immortal warriors who hunt each other through different ages in history. It would give Pattinson the chance to rock a wide-range of weird costumes, and have some light-hearted fun in between the dramatic films he's constantly taking on to try and get as far away from Twilight as possible.
Why It (Probably) Won't Happen: Because the first Highlander didn't do well in theaters. That's just the economics of it. It would likely be a big, expensive blockbuster and Pattinson would also have to bulk up a lot just to carry they giant battle swords those immortal assassins fling around.
