If you really want to know an email to the production company would resolve it. http://www.departure-films.com/about/ Email link at top right. I'm not interested enough in what Alison did or did not sign to bother, but it would take two minutes if anyone was interested to ask the Producer!cj x
You believe the production company would provide a facsimile of the contract used for securing Alison's services including possibly unique details to anyone that asks? Maybe, but I wouldn't count on it. Small chance I'd bet.
