Barely competent pet private eye Ace Ventura is put on the case when kidnappers abduct Snowflake, the Miami Dolphins' mascot. As Ventura tries to unravel the mammal-napping and save the day, the perpetrators have something else in mind.
The voice of Ace Ventura and the manner in which he speaks, was added by Jim Carrey only after several readings of the script. The voice was something Carrey used in his stand up routine. The "All righty then" was the catch phrase of one of his stand up characters and after the lines from the script weren't feeling right, he added it to the script and read through it again using that voice for all the lines. It was such an improvement that it became the main Ace Ventura personality trait.
