The 68th annual Cannes Film Festival is currently being held from 13 to 24 May 2015. Joel and Ethan Coen have been announced as the Presidents of the Jury for the main competition. It is the first time that two people will chair the jury. Since the Coen brothers will each get a separate vote, they will be joined by seven other jurors to form the customary nine-juror panel. French actor Lambert Wilson has been announced as the host for the opening and closing ceremonies.
I have given the link to a wikipedia site which I found better than the official site.
