Time Travel movie

The cult classic "Somewhere in Time" starring Christopher Reeves AKA Superman is about a man who receives a gold watch from an old lady and then he finds out that she is a famous actress (Jane Seymour) from the past. He time travels to the past - 1912 actually and falls in love with her. Sadly, a shiny modern 1979 copper penny pulls him back to his present. He dies of a broken heart. This time travel romance movie was an attempt by "superman" to escape the cape.
