A League of Their Own trivia from The Internet Movie Database (IMDb):

• Tom Hanks gained 30 pounds in preparation for his role. He attributed the weight he gained to a nearby Dairy Queen.

• The characters at the Baseball Hall of Fame, and seen playing as
       the credits roll, are real original players from the league portrayed
       in the film.

• All of the injuries and bruises that are seen in the film were real injuries that the actors received during filming.

• The Peaches played at Beyer Stadium in Rockford, Illinois. No
       place in Rockford could actually be used in the movie because of Beyer
       Stadium's state of disrepair. It was eventually condemned, all that is
       left of the stadium is the original archway and a sign about the
       Peaches.

• Tom Hanks' character, Jimmy Dugan, is loosely based on real-life baseball slugger Jimmie Foxx.

• Actresses auditioning for the film had to prove they could play
       baseball as well. All the actresses cast in the film apart from Geena
       Davis did their own baseball stunts. None of the performers wanted
       stunt doubles.

• Kelly Candaele
       was one of the writers for this movie. His mother played in the league
       portrayed in the movie. Also, Kelly's brother, Casey, was a major
       league infielder from 1986 through 1997. His best season was 1991
       (right before the movie was released) when he collected 121 hits and 50
       RBI for the Houston Astros as their usual starting second baseman.

• When Geena Davis joined the production only days before filming was due to start (she was a late replacement for Debra Winger),
       she was somewhat disadvantaged in that the cast had been baseball
       training for months beforehand. Davis's character was supposed to be
       one of the greatest baseball players in America. Within weeks, however,
       Davis had mastered the game and was regularly beating all her co-stars.

• When announcing the game the Peaches announcer (David L. Lander)
       uses the phrase "Oh Doctor!" during an exciting play. This phrase was
       made popular by 1940s and 50s Brooklyn Dodgers announcer Red Barber.

• For the famous split catch, Geena Davis had to have a stunt double slide into the split. Although Davis could do the splits, as shown, she couldn't slide into it.

• During the filming of the World Series games, the stars would take
       turns entertaining the unpaid extras. Tom Hanks would do puppet shows
       over the dugout, Rosie O'Donnell did stand-up comedy and various actors
       pretended to be Madonna and sang her songs after the singer balked at
       performing for the fans.

• The "strawberry" bruise that Renee Coleman received on her thigh while sliding into a base remained on her for over a year.

• Lori Petty was, in reality, a faster runner than Geena Davis, and
       had to act like she was running slower than Geena Davis and running at
       full speed.

• Rockford Peaches home field in the movie was filmed in
       Huntingburg, Indiana. The stadium was completely renovated and named
       League stadium after the movie crews left. In the movie you can see a
       barn in the background. The barn was actually only two-sided and
       covered a water slide.

• Although she is left-handed, Bitty Schram throws and bats right-handed in the film.

I would have to recommend watching The Final Season.  It just recently came out on DVD, but it is a good baseball movie.

I remember watching Sandlot when I was younger and I really enjoyed it.  I just had my children watch the movie and they also really like it, so it is a good movie that we can sit and watch together.  The unfortunate part of the situation is that they can now almost recite every scene in the movie.

Several good ones mentioned but my most recent favorite would have to be Beer League. While it certainly appeals to a particular adult demographic, it is still quite funny.

Don't forget,,,

"It happens every Spring"

&

"Kill the Umpire"

Never could understand how it came to be called  "SAND-lot"--------when I was a kid we played unorganized city ball on "DIRT-lots."      "Sand" would of been an upgrade!        Asphalt.... school yards, church parking lots, dead end streets/alleys, vacated commercial areas, were also an upgrade.
