It has no been confirmed when the production, which is due to run to 9 November 2013, will reopen.
A press representative said the press night will likely be rescheduled until "the week commencing 23 September."
The play, adapted by Joanna Murray-Smith from Ingmar Bergman's 1970s Swedish TV series, follows Johan and Marianne from happily married couple to warring contenders in divorce and beyond.
Nunn, who directed Iain Glen and his then-wife Imogen Stubbs in the first production at the Belgrade, Coventry in 2008, has revisited the play with Bazeley and actress Olivia Willams in the central roles.
The cast also features Shane Attwooll, Aislinn Sands and Melanie Jessop.
