LOS ANGELES -- Sunday's premiere of The WB's "Jack & Bobby" revealed that it's the youngest McCallister boy, Bobby (Logan Lerman), who will become president of the United States in 2041.

Viewers also learned that his brother, Jack (Matt Long), died before Bobby became president and that Jack's teenage love interest, Courtney Benedict (Jessica Pare) eventually marries Bobby.

"It was a really unique kind of romantic triangle to think that perhaps for the arc of the series the older brother and Courtney would have this equivalent of a teen romance, whether it's unrequited or not," said executive producer Greg Berlanti. "Having Bobby sort of have scenes with his future wife as a young man when there's an obvious age discrepancy and we might not want to see them hook up was really sort of fun dramatically."

Set in the present, "Jack & Bobby" (9 p.m. Sunday) includes mock documentary footage from the future of members of Bobby's administration as well as an adult Courtney and Jack's best friend Marcus Ride (Edwin Hodge), who eventually becomes an adviser to Bobby.

"We thought about having a couple people who were a part of Jack and Bobby's past who had carried into their future was an interesting way of connecting the two time periods," said executive producer Vanessa Taylor. "Additionally, sort of harking back to the Kennedy connection for inspiration, that's obviously a case of people coming from a past and going into the future together."

Berlanti particularly liked the idea of having Jack's best friend, Marcus, end up as an adviser to Jack's brother, Bobby.

"It's sort of that switch of how much of Jack's life does Bobby assume as he becomes an adult?" Berlanti said. "It's a real sort of neat place to start out as the best friend of your older brother and have the character ultimately grow into perhaps your closest both political confidant and ally as an adult."

Berlanti said the decision was made to reveal which brother becomes president because the series lies between the first letter of a sentence and the punctuation mark at the end.

"The series is sort of everything that happens in between," he said. "It's a real distinct challenge in that I think you kind of clearly paint yourself into certain corners. As we go forward with other episodes and we begin to map out the mythology of the McCallister presidency in the future and what it holds for all of us, it's definitely a challenge."

Knowing that Jack dies and Bobby becomes president also gives the producers leeway in how they write the characters in the present.

"With Bobby, every time we sort of watch something horrible happen to him, [we can go], 'Well, that's OK, this kid turns out to be the president of the United States,' " Berlanti said. "And to watch Jack at the same moment have maybe sort of the high school experience we wish we all had where he's sort of a natural hero and things come easier to him but it's kind of tinged with a little bit of tragedy in that this kid meets some sort of unfortunate or untimely end and he's not necessarily there to watch his brother achieve all this."

Executive producer Thomas Schlamme said he hopes viewers will get caught up in putting together the jigsaw pieces to the puzzle of Bobby's life.

"To me, the show is really about watching this child become the visionary that he becomes through all of the things that either help or actually hinder him," he said. "That's the investment the audience is having."
