Re: concept art and set photos!
That is an example of an inept use of an effect best reserved for still photography that has only rarely really worked well in films.
It isn't a matter of being stylistically dated, just that it looks bad, both then (ogod SO bad in the theater you wanted to check your contact lenses) & now. TMP's use of soft or bounce lights didn't help, either. . .
If you want 'stylistically dated' then maybe you should look at Coppola's DRACULA, which used hand-cranked cameras at times (and to pretty good effect.)
The dual-focus diopter lens was popular among certain film directors, including Wise, during the 1970s.
Wise's diopter is no different that JJ's lens flares. Both involve a director using a somewhat popular lens technology in several of their movies, ultimately dating them but the director is primarily concerned with interesting compositions at the time.
