Heartbreaking deleted scenes from Mrs Doubtfire show how incredible Robin Williams was

Just when we thought we'd seen all of Robin Williams' best bits, some deleted scenes emerge and remind us how brilliant of an actor he really was.

Williams sadly passed away in 2014, but his iconic movies are a constant reminder of his talent and his ability to make viewers both laugh and cry.

The 1993 movie Mrs Doubtfire is just one example, with deleted scenes from the movie showcasing his skills.

The movie stars Williams as dad Daniel, who decides to dress up as a female nanny in an attempt to stay close to his kids following a tumultuous divorce from his wife.

One of the deleted scenes shows Daniel attempting to show up for his daughter Lydia at a Spelling Bee, only to cause her to become distracted as he berates his ex-wife for not saving him a seat.

The character becomes emotional later as he attempts to reconcile with Lydia, saying: "I'm sorry. I couldn't control myself, I'm sorry."

"Why can't you just pretend?" Lydia responds. "Pretend to be Mrs Doubtfire and Pudgy the Bird and all those other things. Why can't you and mum just pretend to be happy?"

If he could 'pretend', Lydia argues, they'd 'still be a family'.

As Daniel, Williams then hits viewers right in the feels as he says: "Yeah, we would be, but we'd be a pretend family, you know? It wouldn't be real.

"You'd know. We'd be acting and you can't act 24 hours a day. Life's more real and wonderful than that. Acting is nice but it's a job."

After Lydia claims it's Daniel's 'job' to be a father, he replies: "No, it's not a job. It's a joy being your father. I don't have to play the part of your father, I am your father. I act like a fool but I am your father, OK?

"Always. Rain, shine, it's the one wonderful thing in my life."

Feel the lump in your throat yet?

Another scene is just as emotional, as it features Daniel and his ex, Miranda, arguing after Miranda learns he's been posing as Mrs Doubtfire.

The two adults criticise and shout at each other as the kids listen in, with Miranda telling Daniel: "I cannot forgive you ever."

Daniel then reveals the kids already knew his secret, and claims she was 'the reason for the whole deceit'.

As the parents argue about the kids loving them, Lydia shouts: "I hate you both."

To say the exchanges are tear-jerking would be an understatement - so maybe it's for the best that the producers decided to leave them out of the final cut!
