Lord is from Miami; his mother is a Cuban-born psychologist, and his father retired from the aviation business and before that directed a dance company, Fusion, for 10 years.

During their time at Dartmouth, the school paper published a profile on Miller, which caught the attention of Michael Eisner, then chairman of Disney.

According to Lord, Eisner brought the profile to the attention of his fellow Disney executives who offered to set up a meeting with Miller.

After three months, the two moved to Los Angeles and after one meeting were offered a two-year development deal at Walt Disney Television Animation.

After they wrote and produced on a series of sitcoms, MTV informed the duo that they were interested in purchasing a 13-episode season of Clone High.

After Cloudy with a Chance of Meatballs was released, the two sought to try to make something different and pitched themselves as possible directors for the 21 Jump Street script that Michael Bacall and Jonah Hill had written.

The studio agreed and the two directed their first live-action R-rated film, released to critical acclaim, which led to the production of the sequel 22 Jump Street.

Lin and Warner Bros. loved the take, so Lord and Miller wrote and eventually directed their third feature film together, The Lego Movie.

[12] Lucasfilm announced that "creative differences" were the reason, with Entertainment Weekly reporting that Lord and Miller were going off-script and trying to make the film into more of a comedy.

The series is a murder mystery comedy set at a high school reunion where each episode features a retelling of the same night told through a different character's point of view.

[23][24] In December 2021, Lord and Miller revealed that Across the Spider-Verse was being split into two parts after they had written down the story they wanted to tell for the sequel and realized that it was too much for a single film.

[29] On July 2, 2020, it was announced that MTV Entertainment Studios was developing a revival of Clone High, and that original series creators, Lord, Miller, and Bill Lawrence would be involved with the project.

[37] In October 2023, writer Dennis E. Taylor, author of the Bobiverse series, announced that a potential adaptation had been optioned to Lord Miller Productions for distribution through Universal Pictures.

[40][41] In September 2020, it was announced that a live-action television series based on the character Silk was in development, with both Lord and Miller serving as executive producers alongside Amy Pascal.

[42] The series, which is part of Sony's Spider-Man Universe, would be ordered by MGM+ and Amazon Prime Video under the title Silk: Spider Society, with Angela Kang serving as the showrunner.
