Hard to say where this started first. The posting looks almost simultaneous.
Long and short of it: too early for official comment on the studio or actor’s part. This kind of thing genreally not confirmed until ink is way dry on contract. If you’re a huge name like a Brad Pitt you might comment early, but not a relative unknown. Our gut instinct leans yes because THR tends to get it right moreso than they get it wrong. Bottom line remains to be seen.
