Quantum Leap season 2 premiered on Wednesday, Oct. 4 with season two on NBC. Who’s the cast in this sci-fi series, and what characters do they play? Let’s find out.

Quantum Leap is a revival of the 1990s show of the same name and takes place following the events of its predecessor. Much like the original, Dr. Ben Song’s (Raymond Lee) time leaps through different decades, and it’s up to his dedicated team to figure out why he did it.

At the same time, Song is having quite a journey as he time travels. He meets interesting people, takes on the life of a significant individual, and is educated on the decade’s timeframe. Season 2 will immediately follow season 1’s finale, so fans are jumping right into things!

Season two will return the original cast members and characters while introducing us to some new ones. Raymond Lee plays the series’ protagonist, Dr. Ben Song, with Caitlin Bassett, Mason Alexander Park, Ernie Hudson, and Nanrisa Lee making up the rest of the stellar main cast.

The CW’s The 100‘s Eliza Taylor and ABC’s Once Upon A Time in Wonderland’s Peter Gadiot have been added to season 2, and we’re excited to see their characters as they’ll be excellent additions to the already talented cast.
