After finally making it off the island on his makeshift raft, Chuck Noland (Tom Hanks) realizes his beloved companion Wilson - a painted volleyball - has fallen off and floated beyond his reach.
To make himself look like an average out of shape middle aged man Tom Hanks didn't exercise and allowed himself to grow pudgy. Production was then halted for a year so he could lose fifty pounds and grow out his hair for his time spent on the deserted island. During this hiatus, Robert Zemeckis used the same crew to film What Lies Beneath. - IMBD
