Yannick, a friend of mine, is a hobbyist actor. He is working hard in a theatre troupe called "Singing on the Roof". Despite them being all French people, they love to play in English, mostly Broadway-style musicals. This year, they are going to present "Spamalot", the famous "Monty Python and the Holy Grail" inspired musical comedy. I was more than happy to help them with the poster.
First, my wife and I designed the main concept. We wanted to show some humor, the Grail had of course to be there, and the main characters had to be displayed in a clear way. Moreover, some negative space had to be left around them, for the various texts and stuff that had to be added as well. After a few different tries, we validated a project, and they all came to my place, for a photo shooting session! Needless to say, it was great fun: I had a blast asking them to fool around in their costumes ;-)
The show will happen in Paris, end of June. All the details and credits can be found on their website. You can see the fully finalized version of the poster there too (including the copyrighted Monty Python text that I didn't include here for legal reasons).
