Bobby and Cheryl Strayed, Wild
Relationship: Mother and daughter
Played by: Laura Dern and Reese Witherspoon
Age gap: 9 years
Crunching the numbers: True, 38-year-old Witherspoon is playing younger in the biography adaptation (her same-name, real-life inspiration was 22 when her mother died and 26 when she hiked the Pacific Crest Trail). And, yes, Witherspoon looks excellent for her age, but it's still a stretch for Dern, 47, to be her mother.
