The “No Complementarys” (NC) restriction is imposed for selected films and screenings upon their release. It means that complimentary vouchers/offers are not valid for use on that specific film or screening until the restriction has been lifted. Pre-paid gift cards and gift vouchers are not restricted by the NC restriction.
Generally, the NC restriction will last only 1-2 weeks after a film’s release, although there are exceptions. You can see if a film is NC attribute appearing next to the session time.
