Every time a new Halo rumour is born, Jesus um... Superman punches a unicorn in the testicles. Therefore this latest rumour must be taken with a pinch of the proverbial salt. According to a post by Production Weekly, which was promptly deleted, there is a Halo project in the works being put together by Ridley Scott as producer.
Production Weekly is a website aimed at folks in the movie industry and apparently hires professional researchers in an attempt to compile the most comprehensive list of movies currently in production. This lends credence to the rumours but not to the point where I'd put my mortgage on them being accurate.
And it's all a bit jumbled because, as we know, there is a Halo TV series in production. But what's interesting is that this project and the TV project were listed as separate thing before one was quickly deleted. Paul Scheuring, one of the main writers for Prison Break, is said to be involved.
You can find out more at SciFied, where this rumour currently caught fire. At this stage I'm not ready to declare the project up and running but there is a part of me that would still like to see a Halo movie if one were ever made.
