Sydneysiders, beware.

If you're thinking of seeing the latest adaption of George Orwell's 1984, you should know that audience members have been having some "ungood" reactions. 

Earlier this week, there were reports the stage adaption by British directors Robert Icke and Duncan Macmillan had left people fainting, throwing up and even screaming for mercy. 

Now, it has been confirmed that Australian audiences have been having a similar reaction to the production's notorious torture scenes. 

A spokeswoman told Fairfax Media some audience members have fainted during the Australian tour, which is a co-production between the State Theatre Company of South Australia and the Sydney Theatre Company. 

"We have had a couple of people faint across almost 40 performances playing to about 35,000 people," she said.

"Audiences have by and large loved the show, which has received great word-of-mouth and great reviews. We have had a couple of negative comments about the simulated violence, but nothing untoward." 

To be fair, the show is recommended for mature audiences and warns viewers of "theatrical haze and lighting ... loud effects, the use of blood, and acts of simulated violence".

And, despite the play being too grisly for some, audiences are lapping it up at the box office. 

The play's sold out Sydney run – starring Tom Conroy and Ursula Mills – opens at the Roslyn Packer Theatre on June 28, before moving onto Canberra and Perth in July and August.
