Ray Donovan 10 p.m., Showtime
Showtime’s hot summer series premieres, after the return of “Dexter” at 9, and it has a strong Boston element. Ray, played to calm perfection by Liev Schreiber, lives in L.A., but he is from Southie, and so is the rest of his family. There are Boston accents, but most of them are pain-free. Ray is a “fixer” for powerful Hollywood types, but the one thing he can’t fix is his revenge-filled father, played with Emmy promise by Jon Voight.
Major Crimes 9 p.m., TNT
I was a loyal fan of “The Closer,” and I liked Mary McDonnell on that show. But I haven’t been able to love or even like this spinoff series very much. The crime stories are poorly written, the production values are limited, and the Rusty business is forced. The series is back for the summer, with the second episode finding Flynn undergoing extreme stress.
Gosford Park 8 p.m., Sundance Channel
Oh sure, everyone is all into “Downton Abbey.” But Julian Fellowes started his British estate upstairs-downstairs storytelling with this 2001 Robert Altman film, for which he won a screenplay Oscar. The stars include Helen Mirren, Emily Watson, Kristin Scott Thomas (above, with Ryan Phillippe), and — what’s this? — Maggie Smith.
Franklin & Bash 9 p.m., TNT
Clever move. Franklin and Bash, played by Breckin Meyer and Mark-Paul Gosselaar, are a pair of frat boy lawyers. Now, starting this season, Aaron Spelling’s famous “Lucky Charm” Heather Locklear is on board as the new partner at the law firm who is, essentially, the frat mom.
A Capitol Fourth 8 p.m., Channel 2
Tom Bergeron hosts this celebration, which features Barry Manilow. Oh, you need more? There will also be a couple of “American Idol” singers, Darren Criss from “Glee,” Megan Hilty, and John Williams conducting music from “Lincoln,” plus a mess of fireworks.
Warlocks Rising 9 p.m., Discovery Channel
Move over, Mr. Mojo. This new reality series chronicles the subculture of a motorcycle club in Florida called the Warlocks. It’s another “real-life ‘Sons of Anarchy’,” along with Discovery’s “The Devils Ride.” The Discovery promotional material calls the Warlocks a “secret brotherhood,” so, well, not so secret anymore, guys.
Key Largo 8 p.m., TCM
There aren’t a lot of fresh shows on Saturday nights during the summer — or, actually, any time of year. It’s a good night to catch up on your DVR and On Demand type stuff. BUT: It’s also a good night to submit to one of the great old movies lurking on the schedule, often on TCM. Get with the black and white and watch or rewatch or re-rewatch this 1948 classic from director John Huston, about a gangster holding hostages in Florida in a hurricane. Humphrey Bogart, Lauren Bacall, Lionel Barrymore, and supporting actress Oscar winner Claire Trevor star.
