Honestly, you wonder why they didn't just name him Lonnie Hawkins in the series just to see if anyone would notice and get the in-joke. Anyway, there's a moment in the movie where he's just arrived and has just begun to brief Mel Gibson's character on the situation. When the phone rings and Gibson goes to answer it, Lindo holds the reciever down while he gives Gibson a rundown of how he should handle the call, all while the phone continues to ring and ring and ring. It's a pretty tense scene:
Agent Lonnie Hawkins: "Any demands that come up, now you just agree. You let him know that he's in charge. Your only priority is getting your boy back. Get your boy back, you follow me? Now, you've gotta give us some time, Mr. Mullen. You ask to speak to your son. Ask for some sign that he's alive. Any information you can get. Then tell him he has an allergy. He has some medical condition. You wanna know what kind of weather is he in? Is he indoors? Is he outdoors? ARE WE SET?"
Agent Jack Sickler: "GO!"
Agent Lonnie Hawkins: "Get your boy back."
