Sunday’s Curb Your Enthusiasm episode, which kicked off a story line reuniting Curb star and Seinfeld co-creator Larry David with the cast of Seinfeld, delivered the HBO comedy’s largest audience in more than five years, The Hollywood Reporter reveals.

The return of Jerry Seinfeld, Julia Louis-Dreyfus, Jason Alexander, and Michael Richards attracted 1.6 million viewers, landing Curb’s best performance since March 14, 2004.
