Corrected entry: Midway through the movie, Anthony Hopkins calls Ryan Gosling at Hopkins' office. Hopkins could not possibly know the exact moment Gosling would be at Hopkins' office because Hopkins was in jail at the time.
Correction: This is also a case of a movie villain going for a big flex. They keep vague in the movie itself how he would exactly be able to do that, but there are several possible methods (it was his own company with presumably his own handpicked staff, and throughout the movie, he shows to be in constant touch with private detectives also due to his status as being his own defense attorney) where they actually go for the "how did he do that, come on!" feel. It's not a case of fridge logic plot hole where you have NOT to think of how stupid and implausible it is; the fact that it was out of the ordinary is, on the contrary, the actual point of the scene.
Correction: This is a case of we don't know what was happening behind the scenes. Hopkins could have been trying a few times his office to check and see if Gosling had stopped by. Hopkins would know that Gosling would visit his office at some point to try and ascertain any possible evidence. Lucky perhaps, but it doesn't contradict anything to confirm it being a mistake.
