Davison played a younger, milder, and sometimes much less
confident Doctor. His casting was very much a reaction
to Tom Baker's sometimes over-the-top performance; his characterization
was based somewhat on the first Doctor's portrayal, playing
a less physical Doctor, with Hartnell's tetchiness tempered
by Davison's own youth and mild manner.
Other aspects of
the show established links with the early years of the series:
the Doctor again had three traveling companions, as in the
first stories, two women and a young man. The stories also
frequently had no pause between them, with the ending of
one story leading into the next, something rarely seen since
the early days of Doctor Who.
His first story was Castrovalva, broadcast in January
of 1982, beginning the nineteenth season, and his last was Caves
of Androzani, broadcast in March of 1984.
stories featured several stories with the
Master, and also brought back other old enemies including
the Daleks, the Black Guardian, the Sea Devils, and the
Cybermen. The twentieth season, Davison's second,
included the anniversary story The Five Doctors,
which reunited Davison's Doctor with (most of) his predecessors.
Starting in the late 1990s, Davison reprised the role
on an ongoing basis in the
Big Finish audio stories featuring the fifth Doctor.
More recently, Peter Davison joined David Tennant in the
2007 Children in Need special Time Crash.
