MUD cast Jeff Nichols Sam Shepard image

Whoa. Little Rock director Jeff Nichols has added some serious weight to the cast of “MUD,” which, as we’ve said, started shooting on Monday.

Deadline New York reports that now, in addition to Matthew McConaughey, Reese Witherspoon and Tye Sheridan, the cast includes “Take Shelter” star Michael Shannon and the folks above, Little Rock’s own Ray McKinnon, Sarah Paulson (“Deadwood,” “Martha Marcy May Marlene”), Joe Don Baker (Buford Pusser!) and Pulitzer Prize-winning actor/playwright Sam Shepard (“Days of Heaven”! “Paris, Texas”!)
