The very last line of the song Streisand sings during the big climax performance, "Are you watching me now," is sung with the microphone away from her mouth, revealing it to be lip-synced. Streisand does however mouth the word "now" even though the microphone is still not anywhere near her mouth.
In the swimming pool scene after the motorcycle accident at the stadium concert, John N Howard has Ace bandages on his foot and right hand. Yet, he is shown using the right hand to use a pair of crutches (would be too painful with a wrist sprain). He is also shown swimming, which is also painful to sprained joints. He is not shown wincing at all while swimming. He also puts weight on his right hand as he is getting out of the pool, pushing up on his fingertips on a straightened wrist. This would not be possible without severe pain, if the wrist is in fact damaged enough to require an Ace bandage.
