4. Why did Chris's fortune-hunter friend Harry (Brad Dexter) join the group, even though Chris told him the pay was minimal?
From Quiz The Magnificent Seven
Answer:
He thought Chris wasn't telling him the whole story about the reward.
After Chris put out the word that he was looking for men, Harry showed up: "I heard you got a contract open", but Chris told him it wasn't a job for "a high stepper like you" and that the operation would only pay "a gold eagle, room and board [for] six weeks gunning for some farmers". Harry wasn't convinced: "What's underneath?" and when Chris replied, "Only what I told you", Harry persisted: "Gold? Cattle? Payroll?" He was convinced that Chris was holding back on all the details, and no matter how much Chris said otherwise, Harry decided to join, expecting that the true bounty would eventually be revealed. Although the actor Brad Dexter had over seventy credits during his career, he was probably best-known for his role as Harry Luck in this film. But he did have one other claim to fame: He saved Frank Sinatra from drowning. According to "The New York Times", Sinatra was caught by an undertow while swimming off the coast of Kauai, Hawaii, in 1964, and was 200 yards from shore when Dexter swam out to him and kept him afloat until a surfer was able to pull him ashore on a surfboard.
