Answer by Scott F
Warner Brothers Pictures & Heyday Films are the two production companies.

CEG Media, Cinesite, Double Negative, Gentle Giant Studios, Industrial Light & Magic (ILM), Kerner Optical, Moving Picture Company (MPC), & Rising Sun Pictures are the companies handling the special effects.

There isn’t one specific “talent agency” that represents all the actors in the film. Fiona Weir is the Casting Director.

Nicholas Hooper is the Composer handling the score, along with the Chamber Orchestra of London.
