This is the thread that will cover it. Other information floating around includes: Hathaway will play an archaeologist returning to the US from a dig in Morocco when her brother is injured. She soon falls for her brothers favourite musician, a rock star played by British singer-actor Johnny Flynn. And - Johnathan Rice and Jenny Lewis are writing songs for Flynn to perform, but one track will be reserved for Hathaway.
