I watched Spider-Man: FFH again and I noticed that when Quentin Beck comes to sit with Peter, the camera zooms in, so the real Quentin can sneak in the spot of illusion Quentin without us noticing. Nice attention to detail
Oh that's a cool detail. Another minor thing I noticed is during the rooftop conversation where Beck advises Peter to see MJ, the specifically make sure Peter has no reason to touch Beck or vice versa so that the hologram isn't revealed
