10 surprising ways famous film special effects were made

Submarine

When working on Submarine with Richard Ayoade, the special effects geniuses as Framestore created a digital credits sequence which they then shot out to 35mm film then brought it back to digital to achieve exactly the right kind of grain. "We weren't applying film grain digitally," executive producer Simon Whalley explained to us. "We were putting film grain on by shooting it out to film and then putting it back in. Richard's very, very particular about that. He can really tell the difference."
