I see that the Associated Press obituary mentioned 'Touch of Evil' only in passing as an "eccentric thriller." However, Variety noted that "One of Heston’s finest performances was as a Mexican narcotics investigator in Orson Welles’ 'Touch of Evil,' followed by equally unshowy performances in 'The Big Country' and 'The Wreck of the Mary Deare.' "
The Los Angeles Times stated, Like the chariot race and the bearded prophet Moses, Heston will be best remembered for several indelible cinematic moments: playing a deadly game of cat and mouse with Orson Welles in the oil fields in 'Touch of Evil,'"
Perhaps best of all, The Washington Post wrote, "And he was in a number of first-rate and even a few great movies. His greatest film, 'Touch of Evil,' featured Heston as a Mexican narcotics detective, probably his biggest stretch and not really an outstanding performance. But he was invaluable in getting Universal to put up the money for Orson Welles' s great shaggy dog. It greatness may be incidental to Heston's performance, but its existence certainly isn't incidental to his behind-the-scenes efforts.
