Even if the old-school centurions are brought back, chances are they’ll still be CGI,as was the case in “Razor”.
Had they gone with DeSanto, or Hatch’s “BSGSC” versions, it would have been both Live Action and CG. CG mostly to make the numbers seem larger.
DeSanto’s version was just weeks away from start of principle photography when 9/11 happened, which put production on hold.
During which time, Bonnie Hammer, (Head of SciFi, and former head of Lifetime) used the opportunity to scuttle the production all together, in favor of her preferred version, Ron Moore’s Battlestar 90210.
