Found on Canada's network Global TV, here's a little promo video for LIFE that does include some never-seen-before footage. I'm not really sure if they're aware of it, because it doesn't makes much sense to use such footage to promote the show, but either way, for any fans of the show out there this is great news !
This video does use footage from an early pilot done with different cast members, namely Claudia Black as Charlie's ex-wife Jennifer and Melissa Sagemiller as Charlie's lawyer, Constance Griffiths. And looking at this video, I can see why they decided to recast those roles and I'm pretty happy they did so, because the tones and attitudes just aren't right here.
Constance seems just out of it, not caring, like it's a joke or something, it's totally off. As for Jennifer, she doesn't look like she now does on the show, like she truly believed Charlie was guilty and moved on, has given up on him, their relationship, whatever they shared, and is not willing to let herself go back there and wonder about "what if".
