In J.R.R. Tolkien's The Lord of the Rings, Frodo and his Hobbit companions experienced a couple of dramatic adventures before even arriving at the Prancing Pony. Then, after one of the Nazgûl stabbed Frodo, the Elf-lord Glorfindel brought Frodo to Rivendell. In director Peter Jackson's adaptation, there were no adventures before the Prancing Pony (beyond a close encounter with a Black Rider), and Arwen took Frodo to the House of Elrond. After that, however, they formed the Fellowship of the Ring, and most of Tolkien and Jackson's work synced perfectly.
