As far as the NET profit, TMP can't have been the best ROI for the studio because it cost the most (outside of Nemesis I guess).
Except the claims about TMP's huge budget are largely creative accounting, because Paramount folded in the costs of all the prior, aborted film and TV-revival efforts. Count just the cost of production for TMP itself -- and, okay, for Phase II
, since that was more directly connected to the production than stuff like Planet of the Titans
-- and the figures aren't so high.
