This episode of the StarTalk radio show has astrophysicist Neil deGrasse Tyson and Phil Plait, “The Bad Astronomer,” discuss the Good, the Bad and the Ugly of science in the movies.
Most nerdy part: midway through the podcast they have a contest to see who can point out the most nitpicky science errors in 2001: A Space Odyssey. Near the end of the show, Neil tells the story of how he called out James Cameron for showing the wrong sky at the end of Titanic.
