"Cheers" had an interesting solution to a conflict over who should come first, or perhaps more accurately who should not be second. Ted Danson and Shelley Long both wanted top billing.

The solution was to have Shelley Long on the upper right of the first screen with names and to have Ted Danson on the lower left of that screen. The credits were the consecutive screen type, not the long scroll type, so the two names appeared at the same time.

Long would be read first by someone who read down, and Danson would be read first by someone going left to right. The producers were able to convince both Long and Danson that they were not second.

The rest of the main cast each got a screen afterwards with just their name on it.

When Long left and Kirstie Alley joined the cast as the new female lead and there was now no question than Danson was the star of the show there were no more special screens. Each main cast member got their own screen, with Danson's being the first shown.
