Charlie Trotter film blends the sweet and salty

A new documentary called "Love, Charlie: The Rise and Fall of Chef Charlie Trotter" gets its world premiere Monday at the Chicago International Film Festival.

Why it matters: Trotter may be the most consequential chef Chicago has ever produced. Most portrayals of him come off as either scathing or completely reverential.

• But director Rebecca Halpern goes deeper to find a young dreamer and culinary genius who adopted a punishing persona in order to succeed, and never found his way back.
• She also reveals a man who secretly struggled with brain complications in his final years that left him erratic and misunderstood.

Biggest surprise for Halpern: Through nearly 400 letters Trotter wrote before becoming a chef, Halpern tells Axios she "got to know this young passionate guy named Chuck who loved the Talking Heads, Elvis Costello, Jimi Hendrix and Bob Dylan."

• "He envisioned a life that was rich and full and literary and epic, and he lived it."

Biggest surprise for Monica: That, in 2007, I'd challenged Trotter to a cartwheel contest (that he won) mere hours before he collapsed and was hospitalized for a seizure.

• Later that day he would storm out of the hospital and cook one of his most famous dinners, a celebration of his restaurant's 20th anniversary.

Chicago interviewees in the documentary include chefs Grant Achatz and Carrie Nahabedian, journalist Mark Caro and more.

• Achatz shares stories of their deep rivalry, and also memories of an event Trotter held at his home to urge the food community to support Achatz through his then-cancer battle.

The bottom line: Halpern doesn't dismiss Trotter's infamously bullying behavior, but does try to put it in context:

• "For people who knew him, it's going to reveal a side they've never seen before," she says.

Details: "Love, Charlie" will be presented through in-person and virtual screenings starting Monday. Other Chicago-based documentaries at this year's festival:

"Punch 9 for Harold Washington" about the late mayor.

"Any Given Day" about three local women on probation

"For the Left Hand" about Chicago pianist Norman Malone.
