'The Last Sunrise' Brings Romance, Family Secrets and a Rarely Seen Disease to the Screen

The Last Sunrise is delivering a swoon-worthy romance while bringing awareness to a rare genetic condition.

Based on Anna Todd's novel, the Prime Video film stars Maia Reficco as Oriah "Ry" Pera, a young woman living with tuberous sclerosis complex (TSC) and epilepsy who travels to Mallorca with her protective mother, Isolde, portrayed by Eva Longoria. There, she meets Julián García, played by Fernando Lindez, and begins embracing love, friendship and independence while navigating her health.

Despite their onscreen chemistry, Reficco revealed she and Lindez didn't immediately hit it off.

The actress told E! News they "did not get along" during the first few days together before a night out completely changed their relationship. The costars soon "became besties," forming a friendship that translated to the screen.

Reficco also bonded with Longoria, calling her onscreen mom "hypnotizing" and praising the Desperate Housewives alum for supporting her during a difficult time in her personal life.

For Todd, however, Ry's journey is deeply personal. The After author was inspired by her son, Asher, who lives with TSC and epilepsy.

"For as long as I can remember, every story about someone with chronic illness ends with tragedy," Todd tells OK!. "I wanted to write the opposite – a young woman who has tuberous sclerosis and still gets her love story."

"We get to see her fall in love, make friends and enjoy her life," she continues. "Because so many people with TSC live long, full lives and that hope is real."

TSC is a genetic condition that can cause noncancerous growths or other abnormalities in organs, including the brain, kidneys, heart and eyes.

The film accurately depicts several experiences that can occur with TSC-related epilepsy, including seizures that alter awareness, difficulty controlling seizures with medication and potential medication side effects.

However, some of Ry's medical storyline is dramatized. While brain surgery can be an option for certain people with difficult-to-control seizures, the risk of memory problems depends on the individual. Total memory loss, like the scenario portrayed in the film, would be extremely rare.

There is currently no cure for TSC but treatment and lifelong monitoring can help manage the condition.

Kari Luther Rosbeck, president and CEO of the TSC Alliance, hopes Ry's story introduces the condition to a much larger audience.

"We're excited to see a major film introduce tuberous sclerosis complex to an audience that may never have heard of TSC before," Rosbeck tells OK!. "Representation like this can spark an important conversation and give people a reason to learn more."

"At the same time, TSC is an incredibly complex condition that looks different for every person who lives with it," she continues. "We hope viewers who are moved by Ry's story will take the next step to learn more about TSC and the real people and families affected by it."

Rosbeck adds, "We are grateful to Anna Todd for bringing this story to life inspired by her son Asher."

The Last Sunrise is now streaming on Prime Video.
