As helium auditioned the adjacent 99 radical for the part,  helium continued, "I kept thinking, 'Was that archetypal miss arsenic superb arsenic I thought she was?'" Clearly, she was.

2. Still, she wasn't the lone histrion to beryllium brought successful to trial for the network: She was up against Alona Tal, who would spell connected to play Meg Manning.

3. Veronica's signature style? It was mostly Bell's doing, with the prima telling Vanity Fair, "Rob built her affectional armor successful the discourse of the story. I, on with the prop and costume department, built her carnal armor—her leather jacket, her combat boots, her dark-colored wardrobe. Her container to maine is her binky that has each her weapons and tools successful it."

 "The information is, we ne'er had immoderate volition astatine each for Logan to extremity up with Veronica," Thomas told GQ. "[Dohring] was hired to beryllium the obligatory psychotic jackass. In the writers' room, sitting astir watching dailies, we would each stitchery around, and it was like, 'We privation to ticker that. We privation to ticker those 2 onscreen together.'" Producer Diane Ruggiero added successful an interrogation with Vanity Fair, "Everyone wanted to constitute scenes with them. It was like, 'We person to spell that way.'"

So the end-game shifted, with Dunn revealing to Vanity Fair of the archetypal plan, "Duncan and Veronica were ever meant to beryllium together." 

6.

When Paris Hilton guest starred successful an aboriginal play 1 occurrence arsenic Logan's affluent girlfriend, she had an unusual request on-set: "Rob's adjunct had to bargain Paris Hilton's Chihuahua French fries, due to the fact that the Chihuahua ate McDonald's French fries," Ruggiero recalled. "Me, miss carnal lover, was like, 'Is that each she's feeding that dog, f--king fries?'"

8. The "biggest surprise" for Thomas aboriginal connected was Amanda Seyfried's crook arsenic ill-fated Lilly Kane, revealing to GQ that helium was blown distant by her audition arsenic it was "about 100 times amended than anyone other that we saw, she was conscionable spectacular." Seyfried was truthful good, successful fact, that helium ended up adding successful 4 times much scenes featuring Lilly than helium primitively intended.  

9. Season 1 was built astir 1 main mystery: Who killed Lilly Kane? In the finale, Logan's dad, Aaron Echolls, was revealed arsenic Lilly's killer. While that was ever Thomas' plan, helium astir had to alteration it aft Harry Hamlin booked a movie that would marque him unavailable. Fortunately, Hamlin ended up passing connected that project to film Veronica Mars and Thomas ne'er had to usage his back-up plan: Duncan.

"The enactment from the web was her champion friend's dead, she's been raped, her parent abandoned her, her dada mislaid his job. Can she conscionable person her dad?" Thomas recalled. "It was a truly bully note." Keith and Veronica would spell connected to person 1 of the astir adored father-daughter relationships successful TV history.

12. Oh, Piz. Brought successful arsenic Veronica's caller emotion involvement successful play three, Chris Lowell revealed Thomas had "warned maine retired of the gate, 'You volition beryllium the slightest liked quality connected this show.'" An aggravated emotion triangle and shipper statement commenced, with Lowell receiving truthful overmuch vigor that helium didn't adjacent expect to beryllium asked to instrumentality for the fan-funded movie. 

"Honestly, I legitimately had travel to a spot wherever I was acceptable to judge that I would not beryllium successful the film,'" helium said astatine the 2014 Paleyfest event. "But past Rob sent maine this email saying, 'Hey, by the way, I deliberation we're gonna marque this film. There's really a relation for Piz.' I'm thinking, 'He gets killed. He's the victim.' He's like, 'No, it's really a important part.'" (Spoiler alert: He was inactive dating Veronica.) 

13. Another antheral that vocal "LoVe" fans took to online connection boards to criticize?  Deputy Leo, played by Max Greenfield. Only slated for 1 episode, the New Girl histrion rapidly became a favourite of Thomas and the writers.

Though Thomas work the connection boards frequently, taking notes connected what fans were reacting to, Leo was 1 quality helium refused to change: "Just due to the fact that the viewers aren't raving astir him" helium told Salon successful 2005, "you know, I'm not going to constitute him retired [of the show] conscionable for that, due to the fact that I deliberation he's good, I deliberation helium makes the amusement better."

"It truly was a Hail Mary pass, and the happening that a batch of radical don't cognize is however adjacent it came to succeeding," Thomas told GQ. Alas, The CW decided to cancel the bid completely. "I was blessed we tried it," Thomas said. "Somebody asked me, 'Are you gladsome that that didn't go?' And it's intolerable to know."
