I follow astrophysicist Neil deGrasse Tyson's enlightening and often humorous tweets on Twitter. In fact, he's quite the active Twitter user, and he does tweet about movies from time to time, as an avid watcher himself - especially sci-fi for obvious reasons.
As NPR notes, Tyson pays so much attention to science in movies that he got James Cameron to fix the stars in the sky in Titanic for that movie's recent 3D rerelease.
And oh yeah, he's black :)
In this brief chat with NPR, the director of the Hayden Planetarium, talks to David Greene about this summer's blockbuster movies (specifically, the sci-fi and superhero movies) and how they stack up, in terms of how accurate the science is in them.
They talk the science in Prometheus, Men In Black 3 and The Avengers, so if you haven't seen any of these movies yet, and plan to, you may not want to listen, if you hate your experience spoiled... not that they reveal much. But just a warning.
