BFI Southbank now has a schedule of events listed for September and October; Merlin is not listed as of yet. Last year, the Merlin preview was announced about 4 weeks before the event, which in turn was 2 weeks before the TV premiere. If the rumoured 29 September TV premiere is accurate, an announcement might come in the next couple of weeks, so we’ll keep an eye out for that.
@Chris_Casey42 We don’t have any information regarding a Merlin screening yet, stay tuned…
It’s likely that they just haven’t worked out a time yet - last year’s was organised fairly hastily from what I remember, and wasn’t listed in the schedule when it first came out either.
