Marlon Wayans on “Him,” and on veering from comedy to horror

In the new psychological horror film “Him,” Marlon Wayans plays an aging football superstar tempting a rookie quarterback – who wants to be the greatest – with an evil bargain. Wayans, who juggles films with stand-up, talks with Tracy Smith about how his new role is a big change for someone raised on comedy, and who learned how to turn personal loss into dramatic power.
