In a wildly audacious blend of hidden-camera pranks and heartfelt road-trip comedy, Johnny Knoxville transforms into 86-year-old Irving Zisman, a cantankerous and wildly inappropriate grandfather who embarks on a cross-country journey with his precocious eight-year-old grandson Billy, played by Jackson Nicoll. When Irving’s estranged daughter lands in jail, he is reluctantly tasked with delivering the mischievous boy to his father, setting off a chaotic adventure filled with shockingly candid interactions with unsuspecting members of the public. Directed by Jeff Tremaine and co-written by Spike Jonze, this outrageous film pushes the boundaries of traditional comedy by weaving a surprisingly tender narrative between its most notorious stunts. As the mismatched duo encounters everything from funeral home mishaps to explosive diner chaos and a disastrous beauty pageant, their unlikely bond deepens amidst the mayhem. The movie masterfully balances its signature gross-out humor with genuine emotional beats, showcasing Knoxville’s remarkable commitment to his prosthetic-laden character and Nicoll’s fearless comedic timing. With a running time of just 92 minutes, this R-rated romp delivers nonstop laughter while secretly telling a sweet story about family, acceptance, and the chaos that ensues when societal norms are gleefully shattered.
