This summer’s great wish fulfillment romance is so high stakes, it just might cause an international incident. Taylor Zakhar Perez and Nicholas Galitzine play the U.S. president’s son and a British prince, respectfully, who find themselves falling in love in Matthew López’s winning romcom Red, White & Royal Blue (B+). Considering their roles as high-profile public figures, the young men who Meet Cute at a U.K. wedding party must keep their burgeoning relationship a secret at all costs. The lead actors are dashing and often amusing in their earnest roles, and López grounds the plot with enough political accuracy and contours about making history for one’s culture or community to make the cross-continental complications fairly credible. Strong supporting performances include Uma Thurman as the Texas-accented president and Stephen Fry as a smug member of the monarchy. The film, available on Prime Video, is a triumph of representation and a jolly good time in its own right.
