A loving tribute to veteran casting director Bonnie Timmermann, Simon Wallon’s Bonnie shoots itself in the foot in its opening minutes. As we watch rough VHS tapes documenting the subject’s early interviews with actors like Benicio Del Toro, Natalie Portman and Kate Winslet — all so impossibly young, beautiful and lovable — we already resent the more mundane docu-stuff to come. Why not just gather all these tapes you can get permission for, have Timmermann do a bit of intro and make it a series for streaming? Most movie buffs would watch hours and hours before getting their fill. John Defore
