Hepburn and Spencer Tracy starred in 9 films together over a
span of 25 years (of which they also shared an off-screen relationship).
Most of them are fine films, but to me the one that stands out
as truly great is Adam's Rib (their 6th film together). This
is smartest and funniest Hepburn and Tracy collaboration and
as in all their films together, the chemistry shines. Adam's
Rib is a classic "battle of the sexes" comedy in which
Hepburn plays a lawyer who is happily married to a District
Attorney (played by Tracy). They eventually find themselves
battling on opposite sides of a high-profile marriage case.
Adam's Rib is directed by George Cukor, who always managed to
get great performances from his stars. Cukor especially worked
well with leading ladies, and most particularly Hepburn, whom
he directed on a total of 10 films. Adam's Rib presents generally
equal sympathy for both sides of this "battle of the sexes",
but it does appear Cukor slightly favors Hepburn. Either way,
Adam's Rib is magical and truly funny from start to finish.
This is a classic and the best collaboration of one of film
history's most memorable on-screen duos.
