After the public screening of the film during the Quinzaine des Réalisateurs 2015 (director's fortnight) at Cannes Festival, on the 16th of May 2015, the director and actors present (Benicio Del Toro, Melanie Thierry) received a five minutes standing ovation.
When B (played by Tim Robbins) consults his book regarding getting around the cow in the road, there's a very noticeable coffee ring stain on one of the pages.

Remarkably this stain had no bearing or relation to the Hudsucker Proxy. Its a coincidence.
