Who says they know what they're doing?
DCI (how movies are sent to theaters) does use JPEG2000, but I think they just wanted something with 12-bit video and that's pretty rare in any codec.
One advantage is if you want to decode the same picture at lower resolutions; JPEG can do this equivalent to nearest-neighbor, wavelets can do it equivalent to a better filter than that. But still not as good as just decoding and resizing down.
