It's a nice video, best watched in HD. The large chromatic aberrations show that it was done with a prism filter. Part of the dreamy effect Craig might be liking is due to that chromatic aberration. That exact look will be difficult-to-impossible to emulate in post.
Color aberration is due to the wavelength-by-wavelength action of the prism. A film picture cannot record the original wavelengths, only the original hues. So, for example, a yellow laser line against a dark background will not make color fringes though the prism. But in the film picture, the laser's yellow is 2/3 of the spectrum, green + red, so a post production prism emulator which tries to emulate color aberration, will give the laser line fringes.
In short, there's some danger of a post effect that lacks chromatic aberration and is too clean or one with faked-in chromatic aberration that looks so.
