Movie critic Roger Ebert will resume writing reviews later this month, but will not rejoin his syndicated television show because he is still unable to speak.

In a letter published in Tuesday's Chicago Sun-Times, the Pulitzer Prize winning writer and co-host of the "Ebert & Roeper" television show said a January surgery in Houston ended in complications, and his ability to speak was not restored. He said the return of speech would require another surgery.

"But I still have all my other abilities, including the love of viewing movies and writing about them," Ebert said.

Ebert said he is looking forward to his annual film festival at the University of Illinois on April 23.

"I will resume writing movie reviews shortly thereafter," he said.

Ebert, famous for his "thumbs up" or "thumbs down" critiques, had surgery in 2006 to remove a cancerous growth on his salivary gland. He also had emergency surgery that year after a blood vessel burst near the site of the operation.

He had undergone cancer surgery three times before the 2006 operation — once in 2002 to remove a malignant tumor on his thyroid gland and twice on his salivary gland the following year.

Ebert said he remains cancer-free, and is not ready to think about more surgery.

"I should be content with the abundance I have," he said.

The 10th annual Ebertfest at the University of Illinois runs from April 23 to the 27th. Ebert chose 13 films for the festival.

In addition to Oscar-winning director Ang Lee, other film celebrities expected to attend include "The Sopranos" actor Joey Pantoliano, "Chicago Hope" actress Christine Lahti and director Paul Schrader.
