Wow, talk about some serious overtime! For Sextuplets, Marlon Wayans had to be in the makeup chair for seven hours for a few of the roles before working a full day as the character. Michael Tiddes has worked with Wayans four times prior, directing him in the Haunted House films, Fifty Shades of Black and Naked. He worked with him a lot more in their latest flick! After working a long day as one character, Wayans would come back to set the following day for the next character to do the same exact scene. This process would rinse and repeat throughout the filming of Sextuplets.
