By CHUCK BARNEY Tribune News Service July 9, 2021 DON’T MISS SHARK WEEK One of TV’s biggest summer events – the oceanic Super Bowl, if you will – returns for its 33rd year and runs from Sunday through July 18. Organizers promise 45 hours of see-worthy programming with “bigger sharks and record-breaking breaches,” along with a celebrity guest list that includes Tiffany Haddish, Brad Paisley, JB Smoove, William Shatner, Snoop Dogg, Ian Ziering and Tara Reid. Things kick off with “Crikey! It’s Shark Week” as Robert Irwin attempts to figure out which fierce predator reigns supreme – crocs or great whites? (Sunday, 8 p.m., Discovery Channel; consult listings for other programming on Discovery and discovery+).
