River Song is a fictional character created by Steven Moffat and
played by Alex Kingston in the British science-fiction series Doctor
Who. River Song was introduced to the series as an experienced future
companion of series protagonist the Doctor, an alien Time Lord who
travels through time in his TARDIS. Because River Song is a time
traveller herself, her adventures with the Doctor occur out of
synchronisation; their first meeting (from the audience's perspective)
is his first and apparently her last. While other actresses briefly
portray younger versions of the character, Kingston plays her in 15
episodes, as River becomes a companion, romantic interest and eventual
wife of the Doctor in his eleventh incarnation portrayed by Matt
Smith.River Song was created by Doctor Who writer Steven Moffat for
the show's fourth series in 2008, under the tenure of then executive
producer Russell T Davies. When Moffat took over Davies' duties as
executive producer, he began expanding on the character's background,
depicting adventures earlier in River's timeline, upgrading Alex
Kingston from a guest star to a recurring actor in the series. Other
actresses have subsequently portrayed younger versions of the
character.When the character was first introduced, much about her
origins remained a mystery. Following the character's initial
appearance, Davies had described her as "one of the most important
characters" in the narrative, and "vital" to the Doctor's life. In
series six (2011), Moffat's episodes unveil more about the character.
Born Melody Pond, River is the daughter of the Eleventh Doctor's
companions Amy Pond (Karen Gillan) and Rory Williams (Arthur Darvill),
alongside whom Kingston had already appeared several times in series
five and six of the show. Having been conceived on board the TARDIS as
it travelled through the time vortex, Melody is born with genetic
traits and abilities similar to those of the Doctor's own race, the
Time Lords. River Song (Doctor Who) Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
