The first scene of 'La La Land' changed quite a bit. Originally, "there was pre-intro stuff," Director Damien Chazelle says, including opening credits set to an overture. He'd also intended to begin with Ryan Gosling's and Emma Stone's characters in their cars before launching into the number. Naomie Harris shot her Oscar-nominated role for 'Moonlight' in just three days. Lucas Hedges got his intense 'Manchester by the Sea' performance by staying quiet for a whole day. Mel Gibson instructed a stuntman to lay in dirty water and rats while star Andrew Garfield played dead in 'Hacksaw Ridge'. 'Hidden Figures' star Taraji P. Henson were all retro 1960s attire, including corsets and girdles, to play NASA math hero Katherine Johnson.
