Both parents address words to their absent children which they hope, but cannot know, will reach them. Coop records video messages which he transmits back to Earth, though they will take years to arrive. Stone, meanwhile, speaks to the character who seemed to appear to her as Catholics pray to saints, asking that a message be passed on to her departed daughter.
While neither film’s protagonist is religious, “Gravity” is interested in religion in a way that “Interstellar” isn’t. Convinced that she is doomed to die in space, Stone laments that not only will no one on Earth pray for her soul, she was never even taught to pray and doesn’t know how to pray for her own soul.
Improbably traveling to two different space stations, Stone encounters a Russian Orthodox icon of Saint Christopher carrying the child Jesus in a Russian spacecraft and a smiling Buddha statue in a Chinese spacecraft. (Strikingly, the only analogous object on the American space shuttle is a statue of Marvin the Martian ”” an ironic comment, perhaps, on religiously deracinated Western secularism?)
