Progressive also produced the concept poster below. This one did find its way into use online (I first shared it HERE), but it was never an "official" poster. You can see it carries the wrong air date as well. Below is a photo of Brody doing the photo shoot for this poster with Creative Directors Michael Scalere & Steph Sebbag.
Progressive was also responsible for the final poster as well as several character stills. To see all their work on Houdini visit their official website.
In other Houdini news, noted English actor Tim Pigott-Smith, who played Houdini's (entirely fictional) spymaster "M", passed away last week at age 70. You can read his obituary at TV.BT.
