Richard Linklater filmed a movie in two-week increments over 12 years, tracking a boy’s life from age 6 to 18. The stellar performances of the cast—Ethan Hawke as the distant dad, Patricia Arquette as the hardworking mom, Ellar Coltrane as the boy at the center of it all—feel collaborative and natural. The entire film matures and deepens along with young Coltrane. The ambition behind Boyhood is simply immense, and that ambition pays off with a gorgeous, moving masterpiece of cinema. Tonight, Linklater will be in attendance to celebrate his astonishing achievement. (Egyptian, 801 E Pine St,, 5 pm, $15–$30)
