Attempting to build a TV franchise onto the 1973 hit movie Westworld (and ignoring a previous attempted TV revival in 1980), HBO premieres the first episode of Westworld, starring Anthony Hopkins, Thandie Newton, Ed Harris, and Evan Rachel Wood. The series premiere of the spectacularly expensive, long-delayed show wins a large audience and a cult following.

The CW airs the 47th episode of The Flash, a modern-day reboot of DC Comics’ superhero starring Grant Gustin. This is the series’ third season premiere.
The 93rd episode of Arrow, a modern-day reboot of DC Comics’ Green Arrow superhero starring Stephen Amell, airs on the CW. Chad L. Coleman (The Expanse, The Orville) guest stars in the fifth season premiere.
