Embrace Your Summer Dad Bod. These Movies Show You the Way.

To be fair, the stories of doughy dudes by the water are not always happy ones. The role is usually played for laughs, with extra pounds often symbolizing a defect of character. One thinks of the Russian oligarch Dimitry in the recent eat-the-rich satire “Triangle of Sadness,” lounging on a superyacht in vise-tight swimmers and a libidinally flowing gown, his gut round as the earth. Or the volatile movie executive Jack Lipnick in “Barton Fink,” tyrannically calling the shots in 1940s Hollywood from a poolside recliner, his supersize trunks hitched up to his navel. Or there’s the wetsuited dad that Kevin James plays in the 2010 comedy “Grown Ups,” who clears the pool at an amusement park after his urine turns a patch of water blue.
