Vanity Fair Italy had this to say about the Venice Festival (Translated using google translate)
Now, another high defection rate of disappointment, the British actor Robert Pattinson, who at the 72nd Venice Film Festival in Venice, on Saturday 5, was to present The Childhood of a Leader in the category Horizons.
Unfortunately Robert Pattinson had a setback on the set of The Lost City of Z, which is running these days in Belfast.
For now, the show lacks official confirmation, but it seems there is so little hope.
As for the Deauville Festival, Le Figaro are reporting this......
