Continuity mistake: The two CIA guys are watching the softball game and report the it is the bottom of the ninth - the Senators are winning. In the next scene the Senators are batting. If the Senators are winning why are they batting?
Suggested correction: The Senators are never seen batting. Richard (who is on the Senators) is playing in the infield and lets a ball go by, then the next batter hits him in the head with the ball. After that, Maddy takes him home and as they're driving off, it appears the game is over, presumably with the home team winning, and both teams and umps are gathered on the field talking to each other.
Suggested correction: Tom Hanks play on Senators, and is "out", and opponent is batting. Senators lead 1-0 but opponents 9th field is still blank, so they can win. That's why they play.
Other mistake: When Morris is chasing the ambulance on his bicycle, he gets pushed/bumped towards the picnic table. As he tumbles over the table into the water you can see handle bars attached to the bicycle, however whilst Morris is flying through the air (separately to the bicycle), he is holding a second set of handle bars in his hands. (00:42:50)
Suggested correction: He grabbed onto the handrail bar on the back of the ambulance. That bar broke off, which is why he went straight when the ambulance turned (and the why he has a look of surprise on his face). It's that bar he's seen holding, not handlebars.
