In 1927 the director Cecil B. DeMille cast British-born actor H. B. Warner as Jesus in his famous silent film King of Kings. Warner, who 19 years later played the druggist in It's a Wonderful Life, was kept on a short leash during the filming of King of Kings. Cecil B. DeMille was concerned that any behavior by the lead actor deemed inconsistent with the image of Christ would result in negative publicity for the film.
As a result, DeMille enforced strict measures to ensure that Warner kept up a good Jesus-image (or what DeMille thought would be a good representation of Jesus). Both Warner and his co-star Dorothy Cumming (who played Mary, the mother of Jesus) had to sign agreements that barred them for five years from appearing in film roles that might compromise their "holy" screen images. During the filming, Warner was driven to the set with blinds
drawn, and he wore a black veil as he stepped out of the car. DeMille separated Warner from the other cast members, even forcing him to eat alone every day. Warner couldn't play cards, go to ballgames, ride in a convertible, or go swimming.
Unfortunately, the regimen of rules and regulations didn't make Warner more holy. Instead, all of the pressure to be more Christlike without having the power or forgiveness of Jesus seemed to drive Warner over the edge. During the production of King of Kings, rather than act more like Jesus, Warner merely relapsed into his addiction to alcohol. *
