Actor Ed Asner was rushed to the hospital on Tuesday after he had trouble speaking during a performance of his one-man show in Indiana.

The 83-year-old Hollywood legend was performing his play FDR at the Marquette Pavilion in Gary when the trouble started, according to the Chicago Sun-Times.

Asner reportedly began the performance around 45 minutes late and some fans in attendance stated that he appeared visually disgruntled. Within the first 15 minutes of the show he began to display distressing health signs such as struggling with his lines, which prompted crew members to call an ambulance. The actor apologized to the audience for his medical emergency and promised to return when he was feeling better.

Asner's son Matt updated TMZ on his father's condition: "My dad is doing fine. He was rushed to the hospital yesterday for being disoriented on stage. He is resting now at an Indiana hospital and is doing well and very grumpy, which with him is always a good thing."

His father apparently suffered from exhaustion and the younger Asner addressed rumors that there may have been greater health problems behind the incident.

"He is being assessed right now and what I can say is that it was not a stroke," Matt said. "That much we do know. He was feeling under the weather for a few weeks so he may just need some rest but for now he is just fine."

Ed will reportedly be released from the hospital on Wednesday.

The Emmy winner is best known for his roles on The Mary Tyler Moore and Lou Grant, and for his voice work in the Disney-Pixar animated film Up. He has also served as the president of the Screen Actors Guild. His one-man show FDR features Asner in the role of former U.S. President Franklin Delano Roosevelt.
