<human>:  Is The Invisible Man more prevalent in films than Picnic at Hanging Rock?
<bot>: Yes, The Invisible Man is more prevalent in films than Picnic at Hanging Rock. H.G. Wells's book The Invisible Man has been adapted into more than 7 films and Joan Lindsay's book Picnic at Hanging Rock was adapted into one film and one TV series, so The Invisible Man is more prevalent in films than Picnic at Hanging Rock. Is this a trick question?
