Prominent US entertainment voices have suggested record-breaking release Wonder Woman could be in the running for Oscar nominations, prompting talk the female-centric production may be the superhero movie to finally earn a major accolade from the Academy.

Aside from the posthumous award handed down for Heath Ledger's Joker in 2008's The Dark Knight, superhero movies are generally ignored come Oscars-time. But a recent showing of Wonder Woman held by the Academy was reportedly both well-attended and received.

The Hollywood Reporter's Scott Feinberg said he woke up to "a mailbox full of unsolicited comments" following the screening, which he stresses is highly unusual for any film, especially so far from nomination ballot time, which are generally announced in January.

The release wasn't just received well by those attending and critics (earning a 93 per cent score on Rotten Tomatoes), with the North American box office taking in over $US130 million in a strong show of support from the general public.
