Robin Williams defended his Mrs. Doubtfire co-star Lisa Jakub after she was ... trends now

Robin Williams' on-screen daughter Lisa Jakub revealed that the late actor defended her after she was expelled from high school while filming Mrs. Doubtfire in 1993.

The actress, 45, shared that Williams had noticed she was upset and when she told him her school kicked her out he personally wrote a letter to her principal. 

'I got thrown out of high school on Doubtfire,' Jakub said while appearing on a Mrs. Doubtfire reunion episode with her movie siblings Mara Wilson and Matthew Lawrence, on Lawrence's "Brotherly Love podcast.

'The amazing thing was Robin saw that I was upset,' she recalled.  

'He asked me what was going on. I explained. He wrote a letter to my principal saying that he wanted them to rethink this decision, that I was just trying to pursue my education and my career at the same time and could they please support me in this.'

Lisa explained that she was expelled due to the filming schedule.  

'I'm Canadian. I was attending high school in Canada, then I left for four months to film the movie. We were going to set up this system, pre-internet, where I'd mail my school work back and forth to the school. We did that for a while.'

However, the school decided that the system was not going to continue. 'My school in Canada sent a note saying, "You know, this isn’t working for us anymore. Don't come back."'

Jakub was in the ninth grade at the time and remembered being heartbroken by the news. 

'It was just so heartbreaking, because you know I had this life that was very unusual and that was the one normal thing.'  

Though Robin's letter did not get her re-admitted, Jakub shared that her principal had proudly displayed the letter in his office. 

'This principal got the letter, framed the letter, put it up in the office … and didn't ask me to come back,' she said. 

Lisa later got her GED and studied writing at the University of Virginia.

Elsewhere on the podcast she praised Williams' acting abilities.

'I'd been working for a decade when I started Doubtfire, but we had always used a script. I knew when it was my turn to speak,' she said.

'Then you go on set with Robin, and it's like who the f**k knows what's going to happen now? And so you had to be really present. I had to be present with the other person in the room and I actually had to listen.'

'You're just going to go with it,' she added, 'because he's Robin, and you can trust him.'
