Does any of you know, if a character speaks at the very same time they do an action (for an example, someone smiles as they say something, or starts a car while talking etc.), whether the direction that refers to the action they do should be parenthetical or written as a separated action instruction? If the second option is the one customarily used, is it usual to add 'as they say the next/the last line' next to the instruction?
I've really looked for the answer among all the screenplay format guides and advice I could find online and yet haven't found the answer, so I'd really be EXTREMELY THANKFUL to the one who helps me solve the problem
