There have been several failed attempts to adapt the novel to the screen, initially as a film and later as a series.
- In 2001, Larry Niven reported that a movie deal had been signed and was in the early planning stages.
- In 2004, the Sci-Fi Channel reported that it was developing a Ringworld miniseries.
- In 2013, it was again announced by the channel, now rebranded as Syfy, that a miniseries of the novel was in development. This proposed 4-hour miniseries was being written by Michael R. Perry and would have been a co-production between MGM Television and Universal Cable Productions.
