Robin Williams and John Travolta play lifelong BFFs who are the namesakes of a sports-marketing firm trying to land a Japanese account that’ll set them for life. Into this walk two cherubic 7-year-olds (Conner Rayburn and Ella Bleu Travolta as fraternal twins), the result of a drunken South Beach one-nighter that Williams’ Dan spent with a woman named Vicki (Kelly Preston — yes, Travolta’s wife and Ella Bleu’s actual mother). Dan and Travolta’s “Uncle” Charlie are left to cope with the twosome for two weeks, during which uncomfortable moments melt away as strangers become family. You see where this is going, but kids don’t know the formula. My easily amused 6-year-old thought the copious sight gags were absolutely hysterical.
