Not really. Only a guess that because Silver was a producer on the two Predator flicks and that Alien producers Giler, Hill and Carroll were getting credited on AvP that Silver would be too. Whatever deal Fox cut with Brandywine over Alien sequels probably didn't exist for Predator and Silver.
Brandywine (Giler, Hill, Carroll) had nothing to with AvP, Resurrection, and not a massive amount to do with Alien3 (at least as 'Brandywine'). Best I can tell - based on the different titles in the Alien3 workprint - is that Giler and Hill had a production partnership called Phoenix and Carroll was seperate. Don't think Carroll had anything to do with Aliens or Alien3.
