"Interviewer: You were always honest and open at the time about your displeasure with how Chakotay was utilized on the show. When you raised your concerns, did the powers that be listen?"

"Beltran: Chakotay was kind of a solitary character, at least from season four to seven. I think the first three seasons there were a lot of interesting storylines, and then I think a shift happened in the series after Jerri Taylor left. I think any time that a character has an interpersonal relationship that shows growth, and you could say that clearly about Chakotay and the captain. But after Seska left, it was only that relationship with the captain that had depth to it. Chakotay and Tuvok didn’t have much. Chakotay and Paris didn’t have much. Chakotay and the other characters, there wasn’t much of a relationship there. I always regretted that because there was a lot to explore."

"Theorizing that one could time-travel within his own lifetime, Dr. Sam Beckett stepped into the Quantum Leap accelerator...and vanished. He awoke to find himself trapped in the past, facing mirror images that were not his own, and driven by an unknown force to change history for the better. His only guide on this journey is Al, an observer from his own time, who appears in the form of a hologram that only Sam can see and hear. And so Dr. Beckett finds himself leaping from life to life, striving to put right what once went wrong, and hoping each time that his next leap...will be the leap home!"

"Oh, boy..."

"It all started when a time-travel experiment I was conducting went...a little ca-ca. In the blink of a cosmic clock, I went from quantum physicist...to Air Force test pilot, which could have been fun — if I knew how to fly. Fortunately, I had help: An observer from the project, named Al. Unfortunately, Al's a hologram. So, all he can lend is moral support. Anyway, here I am — bouncing around time, putting things right which once went wrong. A sort of...time-traveling Lone Ranger, with Al as my Tonto; and I don't even need a mask. Oh, boy..."

"Theorizing that one could time-travel within his own lifetime, Dr. Sam Beckett led an elite group of scientists into the desert, to develop a top-secret project known as "Quantum Leap". Pressured to prove his theories or lose funding, Dr. Beckett prematurely stepped into the Project Accelerator — and vanished. He awoke to find himself in the past, suffering from partial amnesia, and facing a mirror image that was not his own. Fortunately, contact with his own time was maintained through brainwave transmissions with Al, the Project Observer, who appears in the form of a hologram that only Dr. Beckett can see and hear. Trapped in the past, Dr. Beckett finds himself leaping from life to life, putting things right that once went wrong, and hoping each time that his next leap will be the leap home."

"When I pitched this idea to Brandon Tartikoff and he told me to explain it to him in twenty seconds so his mother could understand it, I decided not to get into the physical aura aspect of it."

"Their attitude was ‘We’ve been off the air for so long no one is going to care, so let’s just say that Quinn got shot but he’s better now, and let’s pretend the other people never came through the gate with them.’ I know people find this hard to believe, but I argued with them over this for months and got the reputation for being a troublemaker or a loose cannon, because I wouldn’t take ‘no’ for an answer."

"Originally, Ryan was going to be in several episodes at the start of the second season, and I worked out with Jacob Epstein, who was also executive producer that year, the path that Ryan would take. We had in mind three or four shows to do with him. By the fourth show, something shocking was going to happen with him."

"They took the attitude of ‘Oh, we don’t want to get into politics, we don’t want to get into dark humor, we don’t want to get into cerebral stuff. We’ve got four characters, and they’re sliding from world to world, and if they land on the world where everyone’s a pirate, they can chase each other around with swords, so that’s going to be fun. That’s show Number One.’ That was kind of the attitude all year"

"Quinn Mallory: What if you could travel to parallel worlds? The same year, the same Earth, only different dimensions. A world where the Russians rule America... or where your dreams of being superstar came true... or where San Francisco was a maximum-security prison. My friends and I found the gateway. Now the problem is... finding a way back home."

"There's rioting breaking out through the city. Fire is continuing to burn everywhere. Troops are shooting people. My God, I...I don't know why! There's a woman dying in front of me, and no one's helping her! There are conflicting reports about who or what started the chaos. Will someone tell me what's happening? This is madness! What is this world coming to?"

"In 1953, Earth experienced a War of the Worlds. Common bacteria stopped the aliens, but it didn't kill them. Instead, the aliens lapsed into a state of deep hibernation. Now the aliens have been resurrected, more terrifying than before. In 1953, the aliens started taking over the world; today, they're taking over our bodies!"
