If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.

Harry Potter himself, Daniel Radcliffe, visited "Jimmy Kimmel Live" to talk about going undercover as Spider-Man at 2014 Comic-Con. Dan also talked about his recent 25th birthday party; he's the easiest person in the world to surprise for his b-day, apparently. Perhaps the best part of DanRad's stint, though, was when he randomly cut a stranger's hair in the street. He didn't just trim it either, he gave a full buzz cut. Would you trust Harry Potter to cut your hair -- especially when he didn't even bring his wand? Accio common sense!

Vin Diesel was on "The Tonight Show" and talked to Jimmy Fallon about how his "Guardians of the Galaxy" character, Groot, only says three words: "I am Groot." Jimmy tested Vin, having him say the line in multiple languages.

Also on "The Tonight Show," Aubrey Plaza gave fans some admittedly "Unqualified Advice." She should've known the real answer to the universe. (It's 42. Duh.)

David Letterman talked to Chris Pratt, who revealed how much weight he lost for "Guardians of the Galaxy." Except he didn't quite reveal serious numbers. Chris said he worked with a whole team of trainers for the movie, and had to starve himself a bit. When cameras were rolling, he joked, he was about 113 pounds. "And four pounds of that was spray tan."

Dave also talked to Judy Greer about the "Planet of the Apes" franchise and the adorkable ape-related gift she got her husband. She kind of messed it up, but that's OK.

Over on "Chelsea Lately," Chelsea Handler and her panel broke down "The Bachelorette's" embarrassing "After the Final Rose" special. Ross Mathews gave Nick Viall some straight talk -- "Bro, bro, you're being a little b-tch" -- and Chelsea suggested herself for the next Bachelorette.

Seth Meyers talked to Lee Pace of "The Hobbit" and "Guardians of the Galaxy" about his AMC show "Halt and Catch Fire" and meeting fans at Comic-Con. It seems like half of the people at Comic-Con were celebs in disguise. Lee also shared that he knows where Bilbo Baggins is buried...
