Richard Curtis wrote this charming 1999 romantic comedy, which benefits greatly not only from the subtlety and honesty of his dialogue, but from the charisma and chemistry of the two leads: Julia Roberts, playing a variation of her own international superstar persona, and Hugh Grant, playing a sometimes stammering bookstore owner who meets her, falls under her spell, and falls in love. Watch for Rhys Ifans, a supporting-role scene-stealer as the bookseller’s best buddy, Spike (pictured). You may recognize Ifans, all these years later, as Mycroft Holmes, Sherlock’s competitive sibling on CBS’s Elementary.
