John Keegan de Lancie (born 31 October 1984; age 40) played Q (Junior) in the Star Trek: Voyager seventh season episode "Q2". He is the son of John de Lancie and Marnie Mosiman and brother of Owen de Lancie. His father John de Lancie played Q in many Star Trek: The Next Generation and several Voyager episodes, while his mother played the role of Balance in the TNG episode "Loud As A Whisper".
According to an interview with the elder John de Lancie, the younger de Lancie was required to undergo the same interview and audition process for the role of Q (Junior) as any other actor. The younger de Lancie read for the part of Q (Junior) against several competitors and was determined by the Voyager casting director to be the best actor for the part, having also done very well in the audition. The senior de Lancie has mainly clarified this in interviews to dispel any rumors that his son had earned the role as a cameo or strictly due to being the son of the primary Q actor.
He also had roles in the movies Alexander, Who Used to Be Rich Last Sunday, Exit to Eden (with Iman and Stephanie Niznik), and The Velocity of Gary (with Olivia d'Abo), as well as episodes of The Drew Carey Show and Ally McBeal (with Renee E. Goldsberry).
In 2009, he graduated from the University of North Carolina at Chapel Hill with a BA in Peace, War and Defense Studies as well as Arab Cultures. After graduation, he spent another year at the Qasid Institute taking classes in Arabic literature, media and classical grammar. From 2008 to 2009, he was also a Fulbright Fellow at the US Department of State and is currently serving as a US Foreign Service Officer.
