Son-in-law of Joseph Cates.

Inspired the Kevin Kline Mustache Principle, according to movie critic Roger Ebert: Kline always has facial hair in comedies, but is clean-shaven in dramatic roles. There are several exceptions to the rule, most notably In & Out (1997) and Wild Wild West (1999) (although in the latter, he did wear a beard and mustache to play President Ulysses S. Grant).

Kline has played presidents and their doubles twice to date: he played Dave and President Bill Mitchell in Dave (1993), and Artemus Gordon and President Ulysses S. Grant in Wild Wild West (1999).

Brother of producer Kate Kline May.

Has won two Tony awards, the first in 1978 for the role of Bruce Granit in 'On the Twentieth Century', and the second in 1981 for the role of The Pirate King in 'The Pirates of Penzance.'

The Kevin Kline Awards were first presented on March 20, 2006 in honor of the actor, a St. Louis native and Priory School graduate. The awards recognize outstanding achievement in Professional Theatre in the Greater St. Louis Area. They honor theatre artists and productions in over 20 categories. Earlier in 1998 he was inducted to the St. Louis Wall of Fame.

Kevin is the first American actor to receive the Sir John Gielgud Golden Quill Award and was recently honored with the Lucille Lortel Lifetime Achievement Award. In 2004, he was inducted into the Theatre Hall of Fame.

Kline is one of the few actors in history to receive the Academy Award for a comedic acting role (A Fish Called Wanda (1988)).

Has played dual roles in three of his films: Dave (1993), Wild Wild West (1999) and Fierce Creatures (1997). In each film, one of his characters has to impersonate the other one.

Has a star in the St. Louis Walk of Fame located on the Delmar Loop.

The theater at his alma mater, St. Louis Priory School, is named in his honor.

Met future wife Phoebe Cates when she auditioned for the part of Chloe in The Big Chill (1983), that eventually went to `Meg Tilly`.

Though it appears that his feature debut was in Sophie`s Choice (1982), Kline had actually completed The Pirates of Penzance (1983) before going on to co-star with Meryl Streep, but the release of `Pirates` was sufficiently delayed, enabling `Sophie` to receive an earlier release

In 1975, he met with director Steven Spielberg about playing Matt Hooper in Jaws (1975) (Played by Richard Dreyfuss). Kevin said that he knew someone who was an oceanographer and thought he could play one. Spielberg then told him "I don`t want someone who knows someone who is an oceanographer, I want someone who is an oceanographer". Richard Dreyfuss then got the part.
