Trivia: When Tammy is getting ready to hit the road she asks Pearl why she should bring her along. Pearl states she has $6,700 and Tammy agrees to take her along. This is the exact same dollar amount Susan Sarandon (Pearl) asks her boyfriend to wire her in "Thelma and Louise".
Trivia: In real life, Susan Sarandon, who plays Tammy's grandmother, is only 13 years older than Allison Janney (Tammy's mother) and only 24 years older than Melissa McCarthy (Tammy). That also means Janney is only 11 years older than McCarthy.
