Wow. I knew you would know how. Screen writers are simply amazing ....
Will Smith is an A-lister and therefore...indestructible. Just shoot an additional scene showing him slipping out of the room behind the woman and her son, but knocked unconscious or show him being blown free or being miraculously shielded from the explosion by his metal desk. Harrison Ford was shielded from an atom bomb inside a refrigerator.
Piece a cake.
