Larry David says the on-screen reunion of the "Seinfeld" cast will be "tough to beat."

The "Seinfeld" co-creator and "Curb Your Enthusiasm" creator-star says the cast will appear together in the finale of the upcoming seventh season of the HBO comedy series.

It marks the first time in 11 years that Jerry Seinfeld, Julia Louis-Dreyfus, Jason Alexander and Michael Richards have appeared together on screen.

David says the "Seinfeld" stars will appear in five "Curb" episodes during the season in a storyline about the cast reuniting. He says he worked closely with Seinfeld on the show-within-a-show script.

He also says an actual "Seinfeld" reunion is unlikely.

The comments were made at a meeting of the Television Critics Association.
